Create a new browser window using the window parameters specified by
|windowInfo|.

MUST be called on the main thread.

All values will be copied internally and the actual window will
be created on the UI thread. If |request_context| is NULL the global request
context will be used. This function can be called on any browser process
thread and will not block. The optional |extra_info| parameter provides an
opportunity to specify extra information specific to the created browser that
will be passed to cef_render_process_handler_t::on_browser_created() in the
render process.

Perform a single iteration of CEF message loop processing.

  MUST be called from the main thread.

  This function is provided for cases where the CEF message loop must be integrated into an
existing application message loop. Use of this function is not recommended
for most users; use either the cef_run_message_loop() function or
CefSettings.multi_threaded_message_loop if possible. When using this function
care must be taken to balance performance against excessive CPU usage. It is
recommended to enable the CefSettings.external_message_pump option when using
this function so that
cef_browser_process_handler_t::on_schedule_message_pump_work() callbacks can
facilitate the scheduling process. This function should only be called on the
main application thread and only if cef_initialize() is called with a
CefSettings.multi_threaded_message_loop value of false (0). This function
will not block.

This function should be called on the main application thread to initialize
the CEF browser process. The |application| parameter may be NULL. A return
value of true (1) indicates that it succeeded and false (0) indicates that it
failed. The |windows_sandbox_info| parameter is only used on Windows and may
be NULL (see cef_sandbox_win.h for details).

Quit the CEF message loop that was started by calling cef_run_message_loop().

MUST be called from the main thread.

This function should only be called on the main application thread and only
if cef_run_message_loop() was used.

Run the event loop that drives the browser.

MUST be called from the main thread. The event loop will not stop on it's own.

Run the CEF message loop. Use this function instead of an application-
provided message loop to get the best balance between performance and CPU
usage. This function should only be called on the main application thread and
only if cef_initialize() is called with a
CefSettings.multi_threaded_message_loop value of false (0). This function
will block until a quit message is received by the system.

Typically, the way to stop the event loop is to call `(.closeBrowser (.getHost browser) 1)` and install a life span handler. The life span handler will receive a `:on-before-close-event` where it can check if the last browser is being closed and then call `cef-quit-message-loop`. See `map->life-span-handler` for more info.

Provides an opportunity to view and/or modify command-line arguments before
processing by CEF and Chromium. The |process_type| value will be NULL for
the browser process. Do not keep a reference to the cef_command_line_t
object passed to this function. The CefSettings.command_line_args_disabled
value can be used to start with an NULL command-line object. Any values
specified in CefSettings that equate to command-line arguments will be set
before this function is called. Be cautious when using this function to
modify command-line arguments for non-browser processes as this may result
in undefined behavior including crashes.

:on-register-custom-schemes (fn [CefApp,CefSchemeRegistrar]) -> void
Provides an opportunity to register custom schemes. Do not keep a reference
to the |registrar| object. This function is called on the main thread for
each process and the registered schemes should be the same across all
processes.

Return the handler for resource bundle events. If
CefSettings.pack_loading_disabled is true (1) a handler must be returned.
If no handler is returned resources will be loaded from pack files. This
function is called by the browser and render processes on multiple threads.

:get-browser-process-handler (fn [CefApp]) -> CefBrowserProcessHandler
Return the handler for functionality specific to the browser process. This
function is called on multiple threads in the browser process.

they are also pre-filled with some sensible defaults.

:on-audio-stream-started (fn [CefAudioHandler,CefBrowser,CefAudioParameters,int]) -> void
Called on a browser audio capture thread when the browser starts streaming
audio. OnAudioSteamStopped will always be called after
OnAudioStreamStarted; both functions may be called multiple times for the
same browser. |params| contains the audio parameters like sample rate and
channel layout. |channels| is the number of channels.

:on-audio-stream-packet (fn [CefAudioHandler,CefBrowser,Pointer,int,long]) -> void
Called on the audio stream thread when a PCM packet is received for the
stream. |data| is an array representing the raw PCM data as a floating
point type, i.e. 4-byte value(s). |frames| is the number of frames in the
PCM packet. |pts| is the presentation timestamp (in milliseconds since the
Unix Epoch) and represents the time at which the decompressed packet should
be presented to the user. Based on |frames| and the |channel_layout| value
passed to OnAudioStreamStarted you can calculate the size of the |data|
array in bytes.

:on-audio-stream-stopped (fn [CefAudioHandler,CefBrowser]) -> void
Called on the UI thread when the stream has stopped. OnAudioSteamStopped
will always be called after OnAudioStreamStarted; both functions may be
called multiple times for the same stream.

:on-audio-stream-error (fn [CefAudioHandler,CefBrowser,CefStringUtf16]) -> void
Called on the UI or audio stream thread when an error occurred. During the
stream creation phase this callback will be called on the UI thread while

(1) if you do wish to show the default "Save As" dialog.

Make a CefBinaryValue
Structure representing a binary value. Can be used on any process and thread.

:is-valid (fn [CefBinaryValue]) -> int
Returns true (1) if this object is valid. This object may become invalid if
the underlying data is owned by another object (e.g. list or dictionary)
and that other object is then modified or destroyed. Do not call any other
functions if this function returns false (0).

:is-owned (fn [CefBinaryValue]) -> int
Returns true (1) if this object is currently owned by another object.

:is-same (fn [CefBinaryValue,CefBinaryValue]) -> int

underlying value but are not necessarily the same object.

:copy (fn [CefBinaryValue]) -> CefBinaryValue
Returns a copy of this object. The data in this object will also be copied.

:get-size (fn [CefBinaryValue]) -> SizeT
Returns the data size.

:get-data (fn [CefBinaryValue,Pointer,SizeT,SizeT]) -> SizeT

:minimum-cross-axis-size int
Minimum cross axis size.

:default-flex int
Default flex for views when none is specified via CefBoxLayout methods.
Using the preferred size as the basis, free space along the main axis is
distributed to views in the ratio of their flex weights. Similarly, if the
views will overflow the parent, space is subtracted in these ratios. A flex
of 0 means this view is not resized. Flex values must not be negative.

Make a CefBrowser
Structure used to represent a browser window. When used in the browser
process the functions of this structure may be called on any thread unless
otherwise indicated in the comments. When used in the render process the
functions of this structure may only be called on the main thread.

They may be called on any thread in that process unless otherwise indicated
in the comments.

:get-browser (fn [CefBrowserHost]) -> CefBrowser
Returns the hosted browser object.

:close-browser (fn [CefBrowserHost,int]) -> void
Request that the browser close. The JavaScript 'onbeforeunload' event will
be fired. If |force_close| is false (0) the event handler, if any, will be
allowed to prompt the user and the user can optionally cancel the close. If
|force_close| is true (1) the prompt will not be displayed and the close
will proceed. Results in a call to cef_life_span_handler_t::do_close() if
the event handler allows the close or if |force_close| is true (1). See
cef_life_span_handler_t::do_close() documentation for additional usage
information.

:try-close-browser (fn [CefBrowserHost]) -> int
Helper for closing a browser. Call this function from the top-level window
close handler. Internally this calls CloseBrowser(false (0)) if the close
has not yet been initiated. This function returns false (0) while the close
is pending and true (1) after the close has completed. See close_browser()
and cef_life_span_handler_t::do_close() documentation for additional usage
information. This function must be called on the browser process UI thread.

:set-focus (fn [CefBrowserHost,int]) -> void

can only be called on the UI thread.

:set-zoom-level (fn [CefBrowserHost,double]) -> void
Change the zoom level to the specified value. Specify 0.0 to reset the zoom
level. If called on the UI thread the change will be applied immediately.
Otherwise, the change will be applied asynchronously on the UI thread.

:run-file-dialog (fn [CefBrowserHost,int,CefStringUtf16,CefStringUtf16,Pointer,int,CefRunFileDialogCallback]) -> void
Call to run a file chooser dialog. Only a single file chooser dialog may be
pending at any given time. |mode| represents the type of dialog to display.
|title| to the title to be used for the dialog and may be NULL to show the
default title ("Open" or "Save" depending on the mode). |default_file_path|
is the path with optional directory and/or file name component that will be
initially selected in the dialog. |accept_filters| are used to restrict the
selectable file types and may any combination of (a) valid lower-cased MIME
types (e.g. "text/*" or "image/*"), (b) individual file extensions (e.g.
".txt" or ".png"), or (c) combined description and file extension delimited
using "|" and ";" (e.g. "Image Types|.png;.gif;.jpg").
|selected_accept_filter| is the 0-based index of the filter that will be
selected by default. |callback| will be executed after the dialog is
dismissed or immediately if another dialog is already pending. The dialog
will be initiated asynchronously on the UI thread.

:start-download (fn [CefBrowserHost,CefStringUtf16]) -> void
Download the file at |url| using cef_download_handler_t.

:download-image (fn [CefBrowserHost,CefStringUtf16,int,int,int,CefDownloadImageCallback]) -> void
Download |image_url| and execute |callback| on completion with the images
received from the renderer. If |is_favicon| is true (1) then cookies are
not sent and not accepted during download. Images with density independent
pixel (DIP) sizes larger than |max_image_size| are filtered out from the
image results. Versions of the image at different scale factors may be
downloaded up to the maximum scale factor supported by the system. If there
are no image results <= |max_image_size| then the smallest image is resized
to |max_image_size| and is the only result. A |max_image_size| of 0 means
unlimited. If |bypass_cache| is true (1) then |image_url| is requested from
the server even if it is present in the browser cache.

:print (fn [CefBrowserHost]) -> void
Print the current browser contents.

:print-to-pdf (fn [CefBrowserHost,CefStringUtf16,CefPdfPrintSettings,CefPdfPrintCallback]) -> void
Print the current browser contents to the PDF file specified by |path| and
execute |callback| on completion. The caller is responsible for deleting
|path| when done. For PDF printing to work on Linux you must implement the
cef_print_handler_t::GetPdfPaperSize function.

:find (fn [CefBrowserHost,int,CefStringUtf16,int,int,int]) -> void
Search for |searchText|. |identifier| must be a unique ID and these IDs
must strictly increase so that newer requests always have greater IDs than
older requests. If |identifier| is zero or less than the previous ID value
then it will be automatically assigned a new valid ID. |forward| indicates
whether to search forward or backward within the page. |matchCase|
indicates whether the search should be case-sensitive. |findNext| indicates
whether this is the first request or a follow-up. The cef_find_handler_t
instance, if any, returned via cef_client_t::GetFindHandler will be called
to report find results.

:stop-finding (fn [CefBrowserHost,int]) -> void
Cancel all searches that are currently going on.

:show-dev-tools (fn [CefBrowserHost,Pointer,CefClient,CefBrowserSettings,CefPoint]) -> void
Open developer tools (DevTools) in its own browser. The DevTools browser
will remain associated with this browser. If the DevTools browser is
already open then it will be focused, in which case the |windowInfo|,
|client| and |settings| parameters will be ignored. If |inspect_element_at|
is non-NULL then the element at the specified (x,y) location will be
inspected. The |windowInfo| parameter will be ignored if this browser is
wrapped in a cef_browser_view_t.

:close-dev-tools (fn [CefBrowserHost]) -> void
Explicitly close the associated DevTools browser, if any.

:has-dev-tools (fn [CefBrowserHost]) -> int
Returns true (1) if this browser currently has an associated DevTools
browser. Must be called on the browser process UI thread.

:send-dev-tools-message (fn [CefBrowserHost,Pointer,SizeT]) -> int
Send a function call message over the DevTools protocol. |message| must be
a UTF8-encoded JSON dictionary that contains "id" (int), "function"
(string) and "params" (dictionary, optional) values. See the DevTools
protocol documentation at https://chromedevtools.github.io/devtools-
protocol/ for details of supported functions and the expected "params"
dictionary contents. |message| will be copied if necessary. This function
will return true (1) if called on the UI thread and the message was
successfully submitted for validation, otherwise false (0). Validation will
be applied asynchronously and any messages that fail due to formatting
errors or missing parameters may be discarded without notification. Prefer
ExecuteDevToolsMethod if a more structured approach to message formatting
is desired.
Every valid function call will result in an asynchronous function result or
error message that references the sent message "id". Event messages are
received while notifications are enabled (for example, between function
calls for "Page.enable" and "Page.disable"). All received messages will be
delivered to the observer(s) registered with AddDevToolsMessageObserver.
See cef_dev_tools_message_observer_t::OnDevToolsMessage documentation for
details of received message contents.
Usage of the SendDevToolsMessage, ExecuteDevToolsMethod and
AddDevToolsMessageObserver functions does not require an active DevTools
front-end or remote-debugging session. Other active DevTools sessions will
continue to function independently. However, any modification of global
browser state by one session may not be reflected in the UI of other
sessions.
Communication with the DevTools front-end (when displayed) can be logged
for development purposes by passing the `--devtools-protocol-log-
file=<path>` command-line flag.

:execute-dev-tools-method (fn [CefBrowserHost,int,CefStringUtf16,CefDictionaryValue]) -> int
Execute a function call over the DevTools protocol. This is a more
structured version of SendDevToolsMessage. |message_id| is an incremental
number that uniquely identifies the message (pass 0 to have the next number
assigned automatically based on previous values). |function| is the
function name. |params| are the function parameters, which may be NULL. See
the DevTools protocol documentation (linked above) for details of supported
functions and the expected |params| dictionary contents. This function will
return the assigned message ID if called on the UI thread and the message
was successfully submitted for validation, otherwise 0. See the
SendDevToolsMessage documentation for additional usage information.

:add-dev-tools-message-observer (fn [CefBrowserHost,CefDevToolsMessageObserver]) -> CefRegistration
Add an observer for DevTools protocol messages (function results and
events). The observer will remain registered until the returned
Registration object is destroyed. See the SendDevToolsMessage documentation
for additional usage information.

:get-navigation-entries (fn [CefBrowserHost,CefNavigationEntryVisitor,int]) -> void
Retrieve a snapshot of current navigation entries as values sent to the
specified visitor. If |current_only| is true (1) only the current
navigation entry will be sent, otherwise all navigation entries will be
sent.

:replace-misspelling (fn [CefBrowserHost,CefStringUtf16]) -> void
If a misspelled word is currently selected in an editable node calling this
function will replace it with the specified |word|.

:add-word-to-dictionary (fn [CefBrowserHost,CefStringUtf16]) -> void
Add the specified |word| to the spelling dictionary.

:is-window-rendering-disabled (fn [CefBrowserHost]) -> int
Returns true (1) if window rendering is disabled.

:was-resized (fn [CefBrowserHost]) -> void
Notify the browser that the widget has been resized. The browser will first
call cef_render_handler_t::GetViewRect to get the new size and then call
cef_render_handler_t::OnPaint asynchronously with the updated regions. This
function is only used when window rendering is disabled.

:was-hidden (fn [CefBrowserHost,int]) -> void
Notify the browser that it has been hidden or shown. Layouting and
cef_render_handler_t::OnPaint notification will stop when the browser is
hidden. This function is only used when window rendering is disabled.

:notify-screen-info-changed (fn [CefBrowserHost]) -> void
Send a notification to the browser that the screen info has changed. The
browser will then call cef_render_handler_t::GetScreenInfo to update the
screen information with the new values. This simulates moving the webview
window from one display to another, or changing the properties of the
current display. This function is only used when window rendering is
disabled.

:invalidate (fn [CefBrowserHost,int]) -> void
Invalidate the view. The browser will call cef_render_handler_t::OnPaint
asynchronously. This function is only used when window rendering is
disabled.

:send-external-begin-frame (fn [CefBrowserHost]) -> void
Issue a BeginFrame request to Chromium.  Only valid when
cef_window_tInfo::external_begin_frame_enabled is set to true (1).

:send-key-event (fn [CefBrowserHost,CefKeyEvent]) -> void
Send a key event to the browser.

:send-mouse-click-event (fn [CefBrowserHost,CefMouseEvent,int,int,int]) -> void
Send a mouse click event to the browser. The |x| and |y| coordinates are
relative to the upper-left corner of the view.

:send-mouse-move-event (fn [CefBrowserHost,CefMouseEvent,int]) -> void
Send a mouse move event to the browser. The |x| and |y| coordinates are
relative to the upper-left corner of the view.

:send-mouse-wheel-event (fn [CefBrowserHost,CefMouseEvent,int,int]) -> void
Send a mouse wheel event to the browser. The |x| and |y| coordinates are
relative to the upper-left corner of the view. The |deltaX| and |deltaY|
values represent the movement delta in the X and Y directions respectively.
In order to scroll inside select popups with window rendering disabled
cef_render_handler_t::GetScreenPoint should be implemented properly.

:send-touch-event (fn [CefBrowserHost,CefTouchEvent]) -> void
Send a touch event to the browser for a windowless browser.

:send-focus-event (fn [CefBrowserHost,int]) -> void
Send a focus event to the browser.

Send a capture lost event to the browser.

:notify-move-or-resize-started (fn [CefBrowserHost]) -> void
Notify the browser that the window hosting it is about to be moved or
resized. This function is only used on Windows and Linux.

:get-windowless-frame-rate (fn [CefBrowserHost]) -> int
Returns the maximum rate in frames per second (fps) that
cef_render_handler_t:: OnPaint will be called for a windowless browser. The
actual fps may be lower if the browser cannot generate frames at the
requested rate. The minimum value is 1 and the maximum value is 60 (default
30). This function can only be called on the UI thread.

:set-windowless-frame-rate (fn [CefBrowserHost,int]) -> void
Set the maximum rate in frames per second (fps) that cef_render_handler_t::
OnPaint will be called for a windowless browser. The actual fps may be
lower if the browser cannot generate frames at the requested rate. The
minimum value is 1 and the maximum value is 60 (default 30). Can also be
set at browser creation via cef_browser_tSettings.windowless_frame_rate.

:ime-set-composition (fn [CefBrowserHost,CefStringUtf16,SizeT,CefCompositionUnderline,CefRange,CefRange]) -> void
Begins a new composition or updates the existing composition. Blink has a
special node (a composition node) that allows the input function to change
text without affecting other DOM nodes. |text| is the optional text that
will be inserted into the composition node. |underlines| is an optional set
of ranges that will be underlined in the resulting text.
|replacement_range| is an optional range of the existing text that will be
replaced. |selection_range| is an optional range of the resulting text that
will be selected after insertion or replacement. The |replacement_range|
value is only used on OS X.
This function may be called multiple times as the composition changes. When
the client is done making changes the composition should either be canceled
or completed. To cancel the composition call ImeCancelComposition. To
complete the composition call either ImeCommitText or
ImeFinishComposingText. Completion is usually signaled when:
A. The client receives a WM_IME_COMPOSITION message with a GCS_RESULTSTR
flag (on Windows), or;
B. The client receives a "commit" signal of GtkIMContext (on Linux), or;
C. insertText of NSTextInput is called (on Mac).
This function is only used when window rendering is disabled.

:ime-commit-text (fn [CefBrowserHost,CefStringUtf16,CefRange,int]) -> void
Completes the existing composition by optionally inserting the specified
|text| into the composition node. |replacement_range| is an optional range
of the existing text that will be replaced. |relative_cursor_pos| is where
the cursor will be positioned relative to the current cursor position. See
comments on ImeSetComposition for usage. The |replacement_range| and
|relative_cursor_pos| values are only used on OS X. This function is only
used when window rendering is disabled.

:ime-finish-composing-text (fn [CefBrowserHost,int]) -> void
Completes the existing composition by applying the current composition node
contents. If |keep_selection| is false (0) the current selection, if any,
will be discarded. See comments on ImeSetComposition for usage. This
function is only used when window rendering is disabled.

:ime-cancel-composition (fn [CefBrowserHost]) -> void
Cancels the existing composition and discards the composition node contents
without applying them. See comments on ImeSetComposition for usage. This
function is only used when window rendering is disabled.

:drag-target-drag-enter (fn [CefBrowserHost,CefDragData,CefMouseEvent,int]) -> void
Call this function when the user drags the mouse into the web view (before
calling DragTargetDragOver/DragTargetLeave/DragTargetDrop). |drag_data|
should not contain file contents as this type of data is not allowed to be
dragged into the web view. File contents can be removed using
cef_drag_data_t::ResetFileContents (for example, if |drag_data| comes from
cef_render_handler_t::StartDragging). This function is only used when
window rendering is disabled.

:drag-target-drag-over (fn [CefBrowserHost,CefMouseEvent,int]) -> void
Call this function each time the mouse is moved across the web view during
a drag operation (after calling DragTargetDragEnter and before calling
DragTargetDragLeave/DragTargetDrop). This function is only used when window
rendering is disabled.

:drag-target-drag-leave (fn [CefBrowserHost]) -> void
Call this function when the user drags the mouse out of the web view (after
calling DragTargetDragEnter). This function is only used when window
rendering is disabled.

:drag-target-drop (fn [CefBrowserHost,CefMouseEvent]) -> void
Call this function when the user completes the drag operation by dropping
the object onto the web view (after calling DragTargetDragEnter). The
object being dropped is |drag_data|, given as an argument to the previous
DragTargetDragEnter call. This function is only used when window rendering
is disabled.

:drag-source-ended-at (fn [CefBrowserHost,int,int,int]) -> void
Call this function when the drag operation started by a
cef_render_handler_t::StartDragging call has ended either in a drop or by
being cancelled. |x| and |y| are mouse coordinates relative to the upper-
left corner of the view. If the web view is both the drag source and the
drag target then all DragTarget* functions should be called before
DragSource* mthods. This function is only used when window rendering is
disabled.

:drag-source-system-drag-ended (fn [CefBrowserHost]) -> void
Call this function when the drag operation started by a
cef_render_handler_t::StartDragging call has completed. This function may
be called immediately without first calling DragSourceEndedAt to cancel a
drag operation. If the web view is both the drag source and the drag target
then all DragTarget* functions should be called before DragSource* mthods.
This function is only used when window rendering is disabled.

:get-visible-navigation-entry (fn [CefBrowserHost]) -> CefNavigationEntry
Returns the current visible navigation entry for this browser. This
function can only be called on the UI thread.

:set-accessibility-state (fn [CefBrowserHost,int]) -> void
Set accessibility state for all frames. |accessibility_state| may be
default, enabled or disabled. If |accessibility_state| is STATE_DEFAULT
then accessibility will be disabled by default and the state may be further
controlled with the "force-renderer-accessibility" and "disable-renderer-
accessibility" command-line switches. If |accessibility_state| is
STATE_ENABLED then accessibility will be enabled. If |accessibility_state|
is STATE_DISABLED then accessibility will be completely disabled.
For windowed browsers accessibility will be enabled in Complete mode (which
corresponds to kAccessibilityModeComplete in Chromium). In this mode all
platform accessibility objects will be created and managed by Chromium's
internal implementation. The client needs only to detect the screen reader
and call this function appropriately. For example, on macOS the client can
handle the @"AXEnhancedUserStructure" accessibility attribute to detect
VoiceOver state changes and on Windows the client can handle WM_GETOBJECT
with OBJID_CLIENT to detect accessibility readers.
For windowless browsers accessibility will be enabled in TreeOnly mode
(which corresponds to kAccessibilityModeWebContentsOnly in Chromium). In
this mode renderer accessibility is enabled, the full tree is computed, and
events are passed to CefAccessibiltyHandler, but platform accessibility
objects are not created. The client may implement platform accessibility
objects using CefAccessibiltyHandler callbacks if desired.

:set-auto-resize-enabled (fn [CefBrowserHost,int,CefSize,CefSize]) -> void
Enable notifications of auto resize via
cef_display_handler_t::OnAutoResize. Notifications are disabled by default.
|min_size| and |max_size| define the range of allowed sizes.

:get-extension (fn [CefBrowserHost]) -> CefExtension
Returns the extension hosted in this browser or NULL if no extension is
hosted. See cef_request_context_t::LoadExtension for details.

:is-background-host (fn [CefBrowserHost]) -> int
Returns true (1) if this browser is hosting an extension background script.
Background hosts do not have a window and are not displayable. See
cef_request_context_t::LoadExtension for details.

:set-audio-muted (fn [CefBrowserHost,int]) -> void
Set whether the browser's audio is muted.

:is-audio-muted (fn [CefBrowserHost]) -> int
Returns true (1) if the browser's audio is muted.  This function can only
be called on the UI thread.

Structure used to implement browser process callbacks. The functions of this
structure will be called on the browser process main thread unless otherwise
indicated.

:get-cookieable-schemes (fn [CefBrowserProcessHandler,Pointer,Pointer]) -> void
Called on the browser process UI thread to retrieve the list of schemes
that should support cookies. If |include_defaults| is true (1) the default
schemes ("http", "https", "ws" and "wss") will also be supported. Providing
an NULL |schemes| value and setting |include_defaults| to false (0) will
disable all loading and saving of cookies.
This state will apply to the cef_cookie_manager_t associated with the
global cef_request_context_t. It will also be used as the initial state for
any new cef_request_context_ts created by the client. After creating a new
cef_request_context_t the cef_cookie_manager_t::SetSupportedSchemes
function may be called on the associated cef_cookie_manager_t to futher
override these values.

:on-context-initialized (fn [CefBrowserProcessHandler]) -> void
Called on the browser process UI thread immediately after the CEF context
has been initialized.

:on-before-child-process-launch (fn [CefBrowserProcessHandler,CefCommandLine]) -> void

process UI thread when launching a render process and on the browser
process IO thread when launching a GPU or plugin process. Provides an
opportunity to modify the child process command line. Do not keep a
reference to |command_line| outside of this function.

:get-print-handler (fn [CefBrowserProcessHandler]) -> CefPrintHandler
Return the handler for printing on Linux. If a print handler is not
provided then printing will not be supported on the Linux platform.

:on-schedule-message-pump-work (fn [CefBrowserProcessHandler,long]) -> void
Called from any thread when work has been scheduled for the browser process
main (UI) thread. This callback is used in combination with CefSettings.
external_message_pump and cef_do_message_loop_work() in cases where the CEF
message loop must be integrated into an existing application message loop
(see additional comments and warnings on CefDoMessageLoopWork). This
callback should schedule a cef_do_message_loop_work() call to happen on the
main (UI) thread. |delay_ms| is the requested delay in milliseconds. If
|delay_ms| is <= 0 then the call should happen reasonably soon. If
|delay_ms| is > 0 then the call should be scheduled to happen after the
specified delay and any currently pending scheduled call should be
cancelled.

:get-default-client (fn [CefBrowserProcessHandler]) -> CefClient
Return the default client for use with a newly created browser window. If
null is returned the browser will be unmanaged (no callbacks will be
executed for that browser) and application shutdown will be blocked until
the browser window is closed manually. This function is currently only used
with the chrome runtime.

Make a CefBrowserSettings

default values. The consequences of using custom values may not be well
tested. Many of these and other settings can also configured using command-
line switches.

configurable using the "allow-access-from-files" command-line switch.

:web-security cef_state_t
Controls whether web security restrictions (same-origin policy) will be
enforced. Disabling this setting is not recommend as it will allow risky
security behavior such as cross-site scripting (XSS). Also configurable
using the "disable-web-security" command-line switch.

:image-loading cef_state_t
Controls whether image URLs will be loaded from the network. A cached image
will still be rendered if requested. Also configurable using the
"disable-image-loading" command-line switch.

no document color is specified. The alpha component must be either fully
opaque (0xFF) or fully transparent (0x00). If the alpha component is fully
opaque then the RGB components will be used as the background color. If the
alpha component is fully transparent for a windowed browser then the
CefSettings.background_color value will be used. If the alpha component is
fully transparent for a windowless (off-screen) browser then transparent
painting will be enabled.

:accept-language-list cef_string_t
Comma delimited ordered list of language codes without any whitespace that
will be used in the "Accept-Language" HTTP header. May be set globally
using the CefBrowserSettings.accept_language_list value. If both values are

reference to or attempt to access the message outside of this callback.

Make a CefCommandLine
Structure used to create and/or parse command line arguments. Arguments with
'--', '-' and, on Windows, '/' prefixes are considered switches. Switches
will always precede any arguments without switch prefixes. Switches can
optionally have a value specified using the '=' delimiter (e.g.
"-switch=value"). An argument of "--" will terminate switch parsing with all
subsequent tokens, regardless of prefix, being interpreted as non-switch
arguments. Switch names are considered case-insensitive. This structure can
be used before cef_initialize() is called.

Called to execute a command selected from the context menu. Return true (1)
if the command was handled or false (0) for the default implementation. See
cef_menu_id_t for the command ids that have default implementations. All
user-defined command ids should be between MENU_ID_USER_FIRST and
MENU_ID_USER_LAST. |params| will have the same values as what was passed to

Called on the IO thread before a resource request is sent. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. |request|
cannot be modified in this callback. Return true (1) if the specified
cookie can be sent with the request or false (0) otherwise.

:can-save-cookie (fn [CefCookieAccessFilter,CefBrowser,CefFrame,CefRequest,CefResponse,CefCookie]) -> int
Called on the IO thread after a resource response is received. The
|browser| and |frame| values represent the source of the request, and may

Make a CefCookieManager
Structure used for managing cookies. The functions of this structure may be
called on any thread unless otherwise indicated.

:set-supported-schemes (fn [CefCookieManager,Pointer,int,CefCompletionCallback]) -> void
Set the schemes supported by this manager. If |include_defaults| is true
(1) the default schemes ("http", "https", "ws" and "wss") will also be
supported. Calling this function with an NULL |schemes| value and
|include_defaults| set to false (0) will disable all loading and saving of
cookies for this manager. If |callback| is non-NULL it will be executed
asnychronously on the UI thread after the change has been applied. Must be
called before any cookies are accessed.

:visit-all-cookies (fn [CefCookieManager,CefCookieVisitor]) -> int
Visit all cookies on the UI thread. The returned cookies are ordered by
longest path, then by earliest creation date. Returns false (0) if cookies
cannot be accessed.

:visit-url-cookies (fn [CefCookieManager,CefStringUtf16,int,CefCookieVisitor]) -> int
Visit a subset of cookies on the UI thread. The results are filtered by the

HTTP-only cookies will also be included in the results. The returned
cookies are ordered by longest path, then by earliest creation date.
Returns false (0) if cookies cannot be accessed.

:set-cookie (fn [CefCookieManager,CefStringUtf16,CefCookie,CefSetCookieCallback]) -> int
Sets a cookie given a valid URL and explicit user-provided cookie
attributes. This function expects each attribute to be well-formed. It will
check for disallowed characters (e.g. the ';' character is disallowed
within the cookie value attribute) and fail without setting the cookie if
such characters are found. If |callback| is non-NULL it will be executed
asnychronously on the UI thread after the cookie has been set. Returns
false (0) if an invalid URL is specified or if cookies cannot be accessed.

:delete-cookies (fn [CefCookieManager,CefStringUtf16,CefStringUtf16,CefDeleteCookiesCallback]) -> int
Delete all cookies that match the specified parameters. If both |url| and
|cookie_name| values are specified all host and domain cookies matching
both will be deleted. If only |url| is specified all host cookies (but not
domain cookies) irrespective of path will be deleted. If |url| is NULL all
cookies for all hosts and domains will be deleted. If |callback| is non-
NULL it will be executed asnychronously on the UI thread after the cookies
have been deleted. Returns false (0) if a non-NULL invalid URL is specified
or if cookies cannot be accessed. Cookies can alternately be deleted using
the Visit*Cookies() functions.

:flush-store (fn [CefCookieManager,CefCompletionCallback]) -> int
Flush the backing store (if any) to disk. If |callback| is non-NULL it will
be executed asnychronously on the UI thread after the flush is complete.
Returns false (0) if cookies cannot be accessed.

Make a CefCookieVisitor
Structure to implement for visiting cookie values. The functions of this
structure will always be called on the UI thread.

:visit (fn [CefCookieVisitor,CefCookie,int,int,Pointer]) -> int
Method that will be called once for each cookie. |count| is the 0-based

Method that will be called on receipt of a DevTools protocol message.
|browser| is the originating browser instance. |message| is a UTF8-encoded
JSON dictionary representing either a function result or an event.
|message| is only valid for the scope of this callback and should be copied
if necessary. Return true (1) if the message was handled or false (0) if
the message should be further processed and passed to the
OnDevToolsMethodResult or OnDevToolsEvent functions as appropriate.
Method result dictionaries include an "id" (int) value that identifies the
orginating function call sent from cef_browser_host_t::SendDevToolsMessage,
and optionally either a "result" (dictionary) or "error" (dictionary)
value. The "error" dictionary will contain "code" (int) and "message"
(string) values. Event dictionaries include a "function" (string) value and
optionally a "params" (dictionary) value. See the DevTools protocol
documentation at https://chromedevtools.github.io/devtools-protocol/ for
details of supported function calls and the expected "result" or "params"
dictionary contents. JSON dictionaries can be parsed using the CefParseJSON

component that should be initially selected in the dialog. |accept_filters|
are used to restrict the selectable file types and may any combination of
(a) valid lower-cased MIME types (e.g. "text/*" or "image/*"), (b)
individual file extensions (e.g. ".txt" or ".png"), or (c) combined
description and file extension delimited using "|" and ";" (e.g. "Image
Types|.png;.gif;.jpg"). |selected_accept_filter| is the 0-based index of

See https://developer.chrome.com/extensions/manifest for details.

:is-same (fn [CefExtension,CefExtension]) -> int
Returns true (1) if this object is the same extension as |that| object.
Extensions are considered the same if identifier, path and loader context
match.

:get-handler (fn [CefExtension]) -> CefExtensionHandler
Returns the handler for this extension. Will return NULL for internal
extensions or if no handler was passed to
cef_request_context_t::LoadExtension.

:get-loader-context (fn [CefExtension]) -> CefRequestContext
Returns the request context that loaded this extension. Will return NULL
for internal extensions or if the extension has been unloaded. See the
cef_request_context_t::LoadExtension documentation for more information
about loader contexts. Must be called on the browser process UI thread.

:is-loaded (fn [CefExtension]) -> int
Returns true (1) if this extension is currently loaded. Must be called on
the browser process UI thread.

:unload (fn [CefExtension]) -> void
Unload this extension if it is not an internal extension and is currently
loaded. Will result in a call to
cef_extension_handler_t::OnExtensionUnloaded on success.

Make a CefExtensionHandler
Implement this structure to handle events related to browser extensions. The
functions of this structure will be called on the UI thread. See
cef_request_context_t::LoadExtension for information about extension loading.

:on-extension-load-failed (fn [CefExtensionHandler,int]) -> void
Called if the cef_request_context_t::LoadExtension request fails. |result|
will be the error code.

:on-extension-loaded (fn [CefExtensionHandler,CefExtension]) -> void
Called if the cef_request_context_t::LoadExtension request succeeds.
|extension| is the loaded extension.

:on-extension-unloaded (fn [CefExtensionHandler,CefExtension]) -> void
Called after the cef_extension_t::Unload request has completed.

:on-before-background-browser (fn [CefExtensionHandler,CefExtension,CefStringUtf16,Pointer,CefBrowserSettings]) -> int
Called when an extension needs a browser to host a background script
specified via the "background" manifest key. The browser will have no
visible window and cannot be displayed. |extension| is the extension that
is loading the background script. |url| is an internally generated
reference to an HTML page that will be used to load the background script
via a <script> src attribute. To allow creation of the browser optionally
modify |client| and |settings| and return false (0). To cancel creation of
the browser (and consequently cancel load of the background script) return
true (1). Successful creation will be indicated by a call to
cef_life_span_handler_t::OnAfterCreated, and
cef_browser_host_t::IsBackgroundHost will return true (1) for the resulting
browser. See https://developer.chrome.com/extensions/event_pages for more
information about extension background script usage.

:on-before-browser (fn [CefExtensionHandler,CefExtension,CefBrowser,CefBrowser,int,CefStringUtf16,int,Pointer,Pointer,CefBrowserSettings]) -> int
Called when an extension API (e.g. chrome.tabs.create) requests creation of
a new browser. |extension| and |browser| are the source of the API call.
|active_browser| may optionally be specified via the windowId property or
returned via the get_active_browser() callback and provides the default
|client| and |settings| values for the new browser. |index| is the position
value optionally specified via the index property. |url| is the URL that
will be loaded in the browser. |active| is true (1) if the new browser
should be active when opened.  To allow creation of the browser optionally
modify |windowInfo|, |client| and |settings| and return false (0). To
cancel creation of the browser return true (1). Successful creation will be
indicated by a call to cef_life_span_handler_t::OnAfterCreated. Any
modifications to |windowInfo| will be ignored if |active_browser| is
wrapped in a cef_browser_view_t.

:get-active-browser (fn [CefExtensionHandler,CefExtension,CefBrowser,int]) -> CefBrowser
Called when no tabId is specified to an extension API call that accepts a
tabId parameter (e.g. chrome.tabs.*). |extension| and |browser| are the
source of the API call. Return the browser that will be acted on by the API
call or return NULL to act on |browser|. The returned browser must share
the same cef_request_context_t as |browser|. Incognito browsers should not
be considered unless the source extension has incognito access enabled, in
which case |include_incognito| will be true (1).

:can-access-browser (fn [CefExtensionHandler,CefExtension,CefBrowser,int,CefBrowser]) -> int
Called when the tabId associated with |target_browser| is specified to an
extension API call that accepts a tabId parameter (e.g. chrome.tabs.*).
|extension| and |browser| are the source of the API call. Return true (1)
to allow access of false (0) to deny access. Access to incognito browsers
should not be allowed unless the source extension has incognito access
enabled, in which case |include_incognito| will be true (1).

:get-extension-resource (fn [CefExtensionHandler,CefExtension,CefBrowser,CefStringUtf16,CefGetExtensionResourceCallback]) -> int
Called to retrieve an extension resource that would normally be loaded from
disk (e.g. if a file parameter is specified to chrome.tabs.executeScript).
|extension| and |browser| are the source of the resource request. |file| is
the requested relative file path. To handle the resource request return
true (1) and execute |callback| either synchronously or asynchronously. For
the default behavior which reads the resource from the extension directory
on disk return false (0). Localization substitutions will not be applied to
resources handled via this function.

Make a CefFileDialogCallback
Callback structure for asynchronous continuation of file dialog requests.

:cont (fn [CefFileDialogCallback,int,Pointer]) -> void
Continue the file selection. |selected_accept_filter| should be the 0-based
index of the value selected from the accept filters array passed to
cef_dialog_handler_t::OnFileDialog. |file_paths| should be a single value
or a list of values depending on the dialog mode. An NULL |file_paths|
value is treated the same as calling cancel().

:cancel (fn [CefFileDialogCallback]) -> void
Cancel the file selection.

Make a CefFindHandler
Implement this structure to handle events related to find results. The
functions of this structure will be called on the UI thread.

:on-find-result (fn [CefFindHandler,CefBrowser,int,int,CefRect,int,int]) -> void
Called to report find results returned by cef_browser_host_t::find().
|identifer| is the identifier passed to find(), |count| is the number of
matches currently identified, |selectionRect| is the location of where the
match was found (in window coordinates), |activeMatchOrdinal| is the
current position in the search results, and |finalUpdate| is true (1) if
this is the last find notification.

Make a CefFocusHandler
Implement this structure to handle events related to focus. The functions of
this structure will be called on the UI thread.

:on-take-focus (fn [CefFocusHandler,CefBrowser,int]) -> void
Called when the browser component is about to loose focus. For instance, if
focus was on the last HTML element and the user pressed the TAB key. |next|
will be true (1) if the browser is giving focus to the next component and
false (0) if the browser is giving focus to the previous component.

:on-set-focus (fn [CefFocusHandler,CefBrowser,int]) -> int
Called when the browser component is requesting focus. |source| indicates
where the focus request is originating from. Return false (0) to allow the
focus to be set or true (1) to cancel setting the focus.

:on-got-focus (fn [CefFocusHandler,CefBrowser]) -> void
Called when the browser component has received focus.

Make a CefFrame
Structure used to represent a frame in the browser window. When used in the
browser process the functions of this structure may be called on any thread
unless otherwise indicated in the comments. When used in the render process
the functions of this structure may only be called on the main thread.

:is-valid (fn [CefFrame]) -> int
True if this object is currently attached to a valid frame.

:undo (fn [CefFrame]) -> void
Execute undo in this frame.

:redo (fn [CefFrame]) -> void
Execute redo in this frame.

Execute cut in this frame.

:copy (fn [CefFrame]) -> void
Execute copy in this frame.

:paste (fn [CefFrame]) -> void
Execute paste in this frame.

:del (fn [CefFrame]) -> void
Execute delete in this frame.

:select-all (fn [CefFrame]) -> void
Execute select all in this frame.

:view-source (fn [CefFrame]) -> void
Save this frame's HTML source to a temporary file and open it in the
default text viewing application. This function can only be called from the
browser process.

:get-source (fn [CefFrame,CefStringVisitor]) -> void
Retrieve this frame's HTML source as a string sent to the specified
visitor.

:get-text (fn [CefFrame,CefStringVisitor]) -> void
Retrieve this frame's display text as a string sent to the specified
visitor.

:load-request (fn [CefFrame,CefRequest]) -> void
Load the request represented by the |request| object.
WARNING: This function will fail with "bad IPC message" reason
INVALID_INITIATOR_ORIGIN (213) unless you first navigate to the request
origin using some other mechanism (LoadURL, link click, etc).

:load-url (fn [CefFrame,CefStringUtf16]) -> void
Load the specified |url|.

:execute-java-script (fn [CefFrame,CefStringUtf16,CefStringUtf16,int]) -> void
Execute a string of JavaScript code in this frame. The |script_url|
parameter is the URL where the script in question can be found, if any. The
renderer may request this URL to show the developer the source of the
error.  The |start_line| parameter is the base line number to use for error
reporting.

:is-main (fn [CefFrame]) -> int
Returns true (1) if this is the main (top-level) frame.

:is-focused (fn [CefFrame]) -> int
Returns true (1) if this is the focused frame.

:get-name (fn [CefFrame]) -> CefStringUtf16
Returns the name for this frame. If the frame has an assigned name (for
example, set via the iframe "name" attribute) then that value will be
returned. Otherwise a unique name will be constructed based on the frame
parent hierarchy. The main (top-level) frame will always have an NULL name
value.
The resulting string must be freed by calling cef_string_userfree_free().

:get-identifier (fn [CefFrame]) -> long
Returns the globally unique identifier for this frame or < 0 if the
underlying frame does not yet exist.

:get-parent (fn [CefFrame]) -> CefFrame
Returns the parent of this frame or NULL if this is the main (top-level)
frame.

:get-url (fn [CefFrame]) -> CefStringUtf16
Returns the URL currently loaded in this frame.
The resulting string must be freed by calling cef_string_userfree_free().

:get-browser (fn [CefFrame]) -> CefBrowser
Returns the browser that this frame belongs to.

:get-v8context (fn [CefFrame]) -> CefV8context
Get the V8 context associated with the frame. This function can only be
called from the render process.

:visit-dom (fn [CefFrame,CefDomvisitor]) -> void
Visit the DOM document. This function can only be called from the render
process.

:create-urlrequest (fn [CefFrame,CefRequest,CefUrlrequestClient]) -> CefUrlrequest
Create a new URL request that will be treated as originating from this
frame and the associated browser. This request may be intercepted by the
client via cef_resource_request_handler_t or cef_scheme_handler_factory_t.
Use cef_urlrequest_t::Create instead if you do not want the request to have
this association, in which case it may be handled differently (see
documentation on that function). Requests may originate from both the
browser process and the render process.
For requests originating from the browser process:
- POST data may only contain a single element of type PDE_TYPE_FILE or
PDE_TYPE_BYTES.
For requests originating from the render process:
- POST data may only contain a single element of type PDE_TYPE_BYTES.
- If the response contains Content-Disposition or Mime-Type header values
that would not normally be rendered then the response may receive
special handling inside the browser (for example, via the file download
code path instead of the URL request code path).
The |request| object will be marked as read-only after calling this
function.

:send-process-message (fn [CefFrame,int,CefProcessMessage]) -> void
Send a message to the specified |target_process|. Message delivery is not
guaranteed in all cases (for example, if the browser is closing,
navigating, or if the target process crashes). Send an ACK message back
from the target process if confirmation is required.

Make a CefGetExtensionResourceCallback
Callback structure used for asynchronous continuation of
cef_extension_handler_t::GetExtensionResource.

:cont (fn [CefGetExtensionResourceCallback,CefStreamReader]) -> void
Continue the request. Read the resource contents from |stream|.

:cancel (fn [CefGetExtensionResourceCallback]) -> void
Cancel the request.

Make a CefImage
Container for a single image represented at different scale factors. All
image representations should be the same size in density independent pixel
(DIP) units. For example, if the image at scale factor 1.0 is 100x100 pixels
then the image at scale factor 2.0 should be 200x200 pixels -- both images
will display with a DIP size of 100x100 units. The functions of this
structure can be called on any browser process thread.

:is-empty (fn [CefImage]) -> int
Returns true (1) if this Image is NULL.

:is-same (fn [CefImage,CefImage]) -> int
Returns true (1) if this Image and |that| Image share the same underlying
storage. Will also return true (1) if both images are NULL.

:add-bitmap (fn [CefImage,float,int,int,int,int,Pointer,SizeT]) -> int
Add a bitmap image representation for |scale_factor|. Only 32-bit RGBA/BGRA
formats are supported. |pixel_width| and |pixel_height| are the bitmap
representation size in pixel coordinates. |pixel_data| is the array of
pixel data and should be |pixel_width| x |pixel_height| x 4 bytes in size.
|color_type| and |alpha_type| values specify the pixel format.

:add-png (fn [CefImage,float,Pointer,SizeT]) -> int
Add a PNG image representation for |scale_factor|. |png_data| is the image
data of size |png_data_size|. Any alpha transparency in the PNG data will
be maintained.

:add-jpeg (fn [CefImage,float,Pointer,SizeT]) -> int
Create a JPEG image representation for |scale_factor|. |jpeg_data| is the
image data of size |jpeg_data_size|. The JPEG format does not support
transparency so the alpha byte will be set to 0xFF for all pixels.

:get-width (fn [CefImage]) -> SizeT
Returns the image width in density independent pixel (DIP) units.

:get-height (fn [CefImage]) -> SizeT
Returns the image height in density independent pixel (DIP) units.

:has-representation (fn [CefImage,float]) -> int
Returns true (1) if this image contains a representation for
|scale_factor|.

:remove-representation (fn [CefImage,float]) -> int
Removes the representation for |scale_factor|. Returns true (1) on success.

:get-representation-info (fn [CefImage,float,Pointer,Pointer,Pointer]) -> int
Returns information for the representation that most closely matches
|scale_factor|. |actual_scale_factor| is the actual scale factor for the
representation. |pixel_width| and |pixel_height| are the representation
size in pixel coordinates. Returns true (1) on success.

:get-as-bitmap (fn [CefImage,float,int,int,Pointer,Pointer]) -> CefBinaryValue
Returns the bitmap representation that most closely matches |scale_factor|.
Only 32-bit RGBA/BGRA formats are supported. |color_type| and |alpha_type|
values specify the desired output pixel format. |pixel_width| and
|pixel_height| are the output representation size in pixel coordinates.
Returns a cef_binary_value_t containing the pixel data on success or NULL
on failure.

:get-as-png (fn [CefImage,float,int,Pointer,Pointer]) -> CefBinaryValue
Returns the PNG representation that most closely matches |scale_factor|. If
|with_transparency| is true (1) any alpha transparency in the image will be
represented in the resulting PNG data. |pixel_width| and |pixel_height| are
the output representation size in pixel coordinates. Returns a
cef_binary_value_t containing the PNG image data on success or NULL on
failure.

:get-as-jpeg (fn [CefImage,float,int,Pointer,Pointer]) -> CefBinaryValue
Returns the JPEG representation that most closely matches |scale_factor|.
|quality| determines the compression level with 0 == lowest and 100 ==
highest. The JPEG format does not support alpha transparency and the alpha
channel, if any, will be discarded. |pixel_width| and |pixel_height| are
the output representation size in pixel coordinates. Returns a
cef_binary_value_t containing the JPEG image data on success or NULL on
failure.

Make a CefInsets
Structure representing insets.

Make a CefJsdialogCallback
Callback structure used for asynchronous continuation of JavaScript dialog
requests.

:cont (fn [CefJsdialogCallback,int,CefStringUtf16]) -> void
Continue the JS dialog request. Set |success| to true (1) if the OK button
was pressed. The |user_input| value should be specified for prompt dialogs.

Make a CefJsdialogHandler
Implement this structure to handle events related to JavaScript dialogs. The
functions of this structure will be called on the UI thread.

:on-jsdialog (fn [CefJsdialogHandler,CefBrowser,CefStringUtf16,int,CefStringUtf16,CefStringUtf16,CefJsdialogCallback,Pointer]) -> int
Called to run a JavaScript dialog. If |origin_url| is non-NULL it can be
passed to the CefFormatUrlForSecurityDisplay function to retrieve a secure
and user-friendly display string. The |default_prompt_text| value will be
specified for prompt dialogs only. Set |suppress_message| to true (1) and
return false (0) to suppress the message (suppressing messages is
preferable to immediately executing the callback as this is used to detect
presumably malicious behavior like spamming alert messages in
onbeforeunload). Set |suppress_message| to false (0) and return false (0)
to use the default implementation (the default implementation will show one
modal dialog at a time and suppress any additional dialog requests until
the displayed dialog is dismissed). Return true (1) if the application will
use a custom dialog or if the callback has been executed immediately.
Custom dialogs may be either modal or modeless. If a custom dialog is used
the application must execute |callback| once the custom dialog is
dismissed.

:on-before-unload-dialog (fn [CefJsdialogHandler,CefBrowser,CefStringUtf16,int,CefJsdialogCallback]) -> int
Called to run a dialog asking the user if they want to leave a page. Return
false (0) to use the default dialog implementation. Return true (1) if the
application will use a custom dialog or if the callback has been executed
immediately. Custom dialogs may be either modal or modeless. If a custom
dialog is used the application must execute |callback| once the custom
dialog is dismissed.

:on-reset-dialog-state (fn [CefJsdialogHandler,CefBrowser]) -> void
Called to cancel any pending dialogs and reset any saved dialog state. Will
be called due to events like page navigation irregardless of whether any
dialogs are currently pending.

:on-dialog-closed (fn [CefJsdialogHandler,CefBrowser]) -> void
Called when the default implementation dialog is closed.

Make a CefKeyEvent
Structure representing keyboard event information.

:type cef_key_event_type_t
The type of keyboard event.

:modifiers uint32
Bit flags describing any pressed modifier keys. See
cef_event_flags_t for values.

:windows-key-code int
The Windows key code for the key event. This value is used by the DOM
specification. Sometimes it comes directly from the event (i.e. on
Windows) and sometimes it's determined using a mapping function. See
WebCore/platform/chromium/KeyboardCodes.h for the list of values.

:native-key-code int
The actual key code genenerated by the platform.

:is-system-key int
Indicates whether the event is considered a "system key" event (see
http://msdn.microsoft.com/en-us/library/ms646286(VS.85).aspx for details).
This value will always be false on non-Windows platforms.

:character char16
The character generated by the keystroke.

:unmodified-character char16
Same as |character| but unmodified by any concurrently-held modifiers
(except shift). This is useful for working out shortcut keys.

:focus-on-editable-field int
True if the focus is currently on an editable field on the page. This is
useful for determining if standard key events should be intercepted.

Make a CefKeyboardHandler
Implement this structure to handle events related to keyboard input. The
functions of this structure will be called on the UI thread.

:on-pre-key-event (fn [CefKeyboardHandler,CefBrowser,CefKeyEvent,Pointer,Pointer]) -> int
Called before a keyboard event is sent to the renderer. |event| contains
information about the keyboard event. |os_event| is the operating system
event message, if any. Return true (1) if the event was handled or false
(0) otherwise. If the event will be handled in on_key_event() as a keyboard
shortcut set |is_keyboard_shortcut| to true (1) and return false (0).

:on-key-event (fn [CefKeyboardHandler,CefBrowser,CefKeyEvent,Pointer]) -> int
Called after the renderer and JavaScript in the page has had a chance to
handle the event. |event| contains information about the keyboard event.
|os_event| is the operating system event message, if any. Return true (1)
if the keyboard event was handled or false (0) otherwise.

Make a CefLifeSpanHandler
Implement this structure to handle events related to browser life span. The
functions of this structure will be called on the UI thread unless otherwise
indicated.

:on-before-popup (fn [CefLifeSpanHandler,CefBrowser,CefFrame,CefStringUtf16,CefStringUtf16,int,int,CefPopupFeatures,Pointer,Pointer,CefBrowserSettings,Pointer,Pointer]) -> int
Called on the UI thread before a new popup browser is created. The
|browser| and |frame| values represent the source of the popup request. The
|target_url| and |target_frame_name| values indicate where the popup
browser should navigate and may be NULL if not specified with the request.
The |target_disposition| value indicates where the user intended to open
the popup (e.g. current tab, new tab, etc). The |user_gesture| value will
be true (1) if the popup was opened via explicit user gesture (e.g.
clicking a link) or false (0) if the popup opened automatically (e.g. via
the DomContentLoaded event). The |popupFeatures| structure contains
additional information about the requested popup window. To allow creation
of the popup browser optionally modify |windowInfo|, |client|, |settings|
and |no_javascript_access| and return false (0). To cancel creation of the
popup browser return true (1). The |client| and |settings| values will
default to the source browser's values. If the |no_javascript_access| value
is set to false (0) the new browser will not be scriptable and may not be
hosted in the same renderer process as the source browser. Any
modifications to |windowInfo| will be ignored if the parent browser is
wrapped in a cef_browser_view_t. Popup browser creation will be canceled if
the parent browser is destroyed before the popup browser creation completes
(indicated by a call to OnAfterCreated for the popup browser). The
|extra_info| parameter provides an opportunity to specify extra information
specific to the created popup browser that will be passed to
cef_render_process_handler_t::on_browser_created() in the render process.

:on-after-created (fn [CefLifeSpanHandler,CefBrowser]) -> void
Called after a new browser is created. This callback will be the first
notification that references |browser|.

:do-close (fn [CefLifeSpanHandler,CefBrowser]) -> int
Called when a browser has recieved a request to close. This may result
directly from a call to cef_browser_host_t::*close_browser() or indirectly
if the browser is parented to a top-level window created by CEF and the
user attempts to close that window (by clicking the 'X', for example). The
do_close() function will be called after the JavaScript 'onunload' event
has been fired.
An application should handle top-level owner window close notifications by
calling cef_browser_host_t::try_close_browser() or
cef_browser_host_t::CloseBrowser(false (0)) instead of allowing the window
to close immediately (see the examples below). This gives CEF an
opportunity to process the 'onbeforeunload' event and optionally cancel the
close before do_close() is called.
When windowed rendering is enabled CEF will internally create a window or
view to host the browser. In that case returning false (0) from do_close()
will send the standard close notification to the browser's top-level owner
window (e.g. WM_CLOSE on Windows, performClose: on OS X, "delete_event" on
Linux or cef_window_delegate_t::can_close() callback from Views). If the
browser's host window/view has already been destroyed (via view hierarchy
tear-down, for example) then do_close() will not be called for that browser
since is no longer possible to cancel the close.
When windowed rendering is disabled returning false (0) from do_close()
will cause the browser object to be destroyed immediately.
If the browser's top-level owner window requires a non-standard close
notification then send that notification from do_close() and return true
(1).
The cef_life_span_handler_t::on_before_close() function will be called
after do_close() (if do_close() is called) and immediately before the
browser object is destroyed. The application should only exit after
on_before_close() has been called for all existing browsers.
The below examples describe what should happen during window close when the
browser is parented to an application-provided top-level window.
Example 1: Using cef_browser_host_t::try_close_browser(). This is
recommended for clients using standard close handling and windows created
on the browser process UI thread. 1.  User clicks the window close button
which sends a close notification to
the application's top-level window.
2.  Application's top-level window receives the close notification and
calls TryCloseBrowser() (which internally calls CloseBrowser(false)).
TryCloseBrowser() returns false so the client cancels the window close.
3.  JavaScript 'onbeforeunload' handler executes and shows the close
confirmation dialog (which can be overridden via
CefJSDialogHandler::OnBeforeUnloadDialog()).
4.  User approves the close. 5.  JavaScript 'onunload' handler executes. 6.
CEF sends a close notification to the application's top-level window
(because DoClose() returned false by default).
7.  Application's top-level window receives the close notification and
calls TryCloseBrowser(). TryCloseBrowser() returns true so the client
allows the window close.
8.  Application's top-level window is destroyed. 9.  Application's
on_before_close() handler is called and the browser object
is destroyed.
10. Application exits by calling cef_quit_message_loop() if no other
browsers
exist.
Example 2: Using cef_browser_host_t::CloseBrowser(false (0)) and
implementing the do_close() callback. This is recommended for clients using
non-standard close handling or windows that were not created on the browser
process UI thread. 1.  User clicks the window close button which sends a
close notification to
the application's top-level window.
2.  Application's top-level window receives the close notification and:
A. Calls CefBrowserHost::CloseBrowser(false).
B. Cancels the window close.
3.  JavaScript 'onbeforeunload' handler executes and shows the close
confirmation dialog (which can be overridden via
CefJSDialogHandler::OnBeforeUnloadDialog()).
4.  User approves the close. 5.  JavaScript 'onunload' handler executes. 6.
Application's do_close() handler is called. Application will:
A. Set a flag to indicate that the next close attempt will be allowed.
B. Return false.
7.  CEF sends an close notification to the application's top-level window.
8.  Application's top-level window receives the close notification and
allows the window to close based on the flag from #6B.
9.  Application's top-level window is destroyed. 10. Application's
on_before_close() handler is called and the browser object
is destroyed.
11. Application exits by calling cef_quit_message_loop() if no other
browsers
exist.

:on-before-close (fn [CefLifeSpanHandler,CefBrowser]) -> void
Called just before a browser is destroyed. Release all references to the
browser object and do not attempt to execute any functions on the browser
object (other than GetIdentifier or IsSame) after this callback returns.
This callback will be the last notification that references |browser| on
the UI thread. Any in-progress network requests associated with |browser|
will be aborted when the browser is destroyed, and
cef_resource_request_handler_t callbacks related to those requests may
still arrive on the IO thread after this function is called. See do_close()
documentation for additional usage information.

Make a CefListValue
Structure representing a list value. Can be used on any process and thread.

:is-valid (fn [CefListValue]) -> int
Returns true (1) if this object is valid. This object may become invalid if
the underlying data is owned by another object (e.g. list or dictionary)
and that other object is then modified or destroyed. Do not call any other
functions if this function returns false (0).

:is-owned (fn [CefListValue]) -> int
Returns true (1) if this object is currently owned by another object.

:is-read-only (fn [CefListValue]) -> int
Returns true (1) if the values of this object are read-only. Some APIs may
expose read-only objects.

:is-same (fn [CefListValue,CefListValue]) -> int
Returns true (1) if this object and |that| object have the same underlying
data. If true (1) modifications to this object will also affect |that|
object and vice-versa.

:is-equal (fn [CefListValue,CefListValue]) -> int
Returns true (1) if this object and |that| object have an equivalent
underlying value but are not necessarily the same object.

:copy (fn [CefListValue]) -> CefListValue
Returns a writable copy of this object.

:set-size (fn [CefListValue,SizeT]) -> int
Sets the number of values. If the number of values is expanded all new
value slots will default to type null. Returns true (1) on success.

:get-size (fn [CefListValue]) -> SizeT
Returns the number of values.

Make a CefRequestContext
A request context provides request handling for a set of related browser or
URL request objects. A request context can be specified when creating a new
browser via the cef_browser_host_t static factory functions or when creating
a new URL request via the cef_urlrequest_t static factory functions. Browser
objects with different request contexts will never be hosted in the same
render process. Browser objects with the same request context may or may not
be hosted in the same render process depending on the process model. Browser
objects created indirectly via the JavaScript window.open function or
targeted links will share the same render process and the same request
context as the source browser. When running in single-process mode there is
only a single render process (the main process) and so all browsers created
in single-process mode will share the same request context. This will be the
first request context passed into a cef_browser_host_t static factory
function and all other request context objects will be ignored.

:is-same (fn [CefRequestContext,CefRequestContext]) -> int

context argument.

:get-handler (fn [CefRequestContext]) -> CefRequestContextHandler
Returns the handler for this context if any.

:get-cache-path (fn [CefRequestContext]) -> CefStringUtf16
Returns the cache path for this object. If NULL an "incognito mode" in-
memory cache is being used.
The resulting string must be freed by calling cef_string_userfree_free().

:get-cookie-manager (fn [CefRequestContext,CefCompletionCallback]) -> CefCookieManager
Returns the cookie manager for this object. If |callback| is non-NULL it
will be executed asnychronously on the IO thread after the manager's
storage has been initialized.

:register-scheme-handler-factory (fn [CefRequestContext,CefStringUtf16,CefStringUtf16,CefSchemeHandlerFactory]) -> int
Register a scheme handler factory for the specified |scheme_name| and
optional |domain_name|. An NULL |domain_name| value for a standard scheme
will cause the factory to match all domain names. The |domain_name| value
will be ignored for non-standard schemes. If |scheme_name| is a built-in
scheme and no handler is returned by |factory| then the built-in scheme
handler factory will be called. If |scheme_name| is a custom scheme then
you must also implement the cef_app_t::on_register_custom_schemes()
function in all processes. This function may be called multiple times to
change or remove the factory that matches the specified |scheme_name| and
optional |domain_name|. Returns false (0) if an error occurs. This function
may be called on any thread in the browser process.

:clear-scheme-handler-factories (fn [CefRequestContext]) -> int

This function may be called on any thread in the browser process.

:purge-plugin-list-cache (fn [CefRequestContext,int]) -> void
Tells all renderer processes associated with this context to throw away
their plugin list cache. If |reload_pages| is true (1) they will also
reload all pages with plugins.
cef_request_context_handler_t::OnBeforePluginLoad may be called to rebuild
the plugin list cache.

:has-preference (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if a preference with the specified |name| exists. This
function must be called on the browser process UI thread.

:get-preference (fn [CefRequestContext,CefStringUtf16]) -> CefValue
Returns the value for the preference with the specified |name|. Returns
NULL if the preference does not exist. The returned object contains a copy
of the underlying preference value and modifications to the returned object
will not modify the underlying preference value. This function must be
called on the browser process UI thread.

:get-all-preferences (fn [CefRequestContext,int]) -> CefDictionaryValue
Returns all preferences as a dictionary. If |include_defaults| is true (1)
then preferences currently at their default value will be included. The
returned object contains a copy of the underlying preference values and
modifications to the returned object will not modify the underlying
preference values. This function must be called on the browser process UI
thread.

:can-set-preference (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if the preference with the specified |name| can be
modified using SetPreference. As one example preferences set via the
command-line usually cannot be modified. This function must be called on
the browser process UI thread.

:set-preference (fn [CefRequestContext,CefStringUtf16,CefValue,CefStringUtf16]) -> int
Set the |value| associated with preference |name|. Returns true (1) if the
value is set successfully and false (0) otherwise. If |value| is NULL the
preference will be restored to its default value. If setting the preference
fails then |error| will be populated with a detailed description of the
problem. This function must be called on the browser process UI thread.

:clear-certificate-exceptions (fn [CefRequestContext,CefCompletionCallback]) -> void
Clears all certificate exceptions that were added as part of handling
cef_request_handler_t::on_certificate_error(). If you call this it is
recommended that you also call close_all_connections() or you risk not
being prompted again for server certificates if you reconnect quickly. If
|callback| is non-NULL it will be executed on the UI thread after
completion.

:clear-http-auth-credentials (fn [CefRequestContext,CefCompletionCallback]) -> void
Clears all HTTP authentication credentials that were added as part of
handling GetAuthCredentials. If |callback| is non-NULL it will be executed
on the UI thread after completion.

:close-all-connections (fn [CefRequestContext,CefCompletionCallback]) -> void
Clears all active and idle connections that Chromium currently has. This is
only recommended if you have released all other CEF objects but don't yet
want to call cef_shutdown(). If |callback| is non-NULL it will be executed
on the UI thread after completion.

:resolve-host (fn [CefRequestContext,CefStringUtf16,CefResolveCallback]) -> void
Attempts to resolve |origin| to a list of associated IP addresses.
|callback| will be executed on the UI thread after completion.

:load-extension (fn [CefRequestContext,CefStringUtf16,CefDictionaryValue,CefExtensionHandler]) -> void
Load an extension.
If extension resources will be read from disk using the default load
implementation then |root_directory| should be the absolute path to the
extension resources directory and |manifest| should be NULL. If extension
resources will be provided by the client (e.g. via cef_request_handler_t
and/or cef_extension_handler_t) then |root_directory| should be a path
component unique to the extension (if not absolute this will be internally
prefixed with the PK_DIR_RESOURCES path) and |manifest| should contain the
contents that would otherwise be read from the "manifest.json" file on
disk.
The loaded extension will be accessible in all contexts sharing the same
storage (HasExtension returns true (1)). However, only the context on which
this function was called is considered the loader (DidLoadExtension returns
true (1)) and only the loader will receive cef_request_context_handler_t
callbacks for the extension.
cef_extension_handler_t::OnExtensionLoaded will be called on load success
or cef_extension_handler_t::OnExtensionLoadFailed will be called on load
failure.
If the extension specifies a background script via the "background"
manifest key then cef_extension_handler_t::OnBeforeBackgroundBrowser will
be called to create the background browser. See that function for
additional information about background scripts.
For visible extension views the client application should evaluate the
manifest to determine the correct extension URL to load and then pass that
URL to the cef_browser_host_t::CreateBrowser* function after the extension
has loaded. For example, the client can look for the "browser_action"
manifest key as documented at
https://developer.chrome.com/extensions/browserAction. Extension URLs take
the form "chrome-extension://<extension_id>/<path>".
Browsers that host extensions differ from normal browsers as follows:
- Can access chrome.* JavaScript APIs if allowed by the manifest. Visit
chrome://extensions-support for the list of extension APIs currently
supported by CEF.
- Main frame navigation to non-extension content is blocked.
- Pinch-zooming is disabled.
- CefBrowserHost::GetExtension returns the hosted extension.
- CefBrowserHost::IsBackgroundHost returns true for background hosts.
See https://developer.chrome.com/extensions for extension implementation
and usage documentation.

:did-load-extension (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if this context was used to load the extension identified
by |extension_id|. Other contexts sharing the same storage will also have
access to the extension (see HasExtension). This function must be called on
the browser process UI thread.

:has-extension (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if this context has access to the extension identified by
|extension_id|. This may not be the context that was used to load the
extension (see DidLoadExtension). This function must be called on the
browser process UI thread.

:get-extensions (fn [CefRequestContext,Pointer]) -> int
Retrieve the list of all extensions that this context has access to (see
HasExtension). |extension_ids| will be populated with the list of extension
ID values. Returns true (1) on success. This function must be called on the
browser process UI thread.

:get-extension (fn [CefRequestContext,CefStringUtf16]) -> CefExtension
Returns the extension matching |extension_id| or NULL if no matching
extension is accessible in this context (see HasExtension). This function
must be called on the browser process UI thread.

:get-media-router (fn [CefRequestContext]) -> CefMediaRouter
Returns the MediaRouter object associated with this context.

Make a CefRequestContextHandler
Implement this structure to provide handler implementations. The handler
instance will not be released until all objects related to the context have
been destroyed.

:on-request-context-initialized (fn [CefRequestContextHandler,CefRequestContext]) -> void
Called on the browser process UI thread immediately after the request
context has been initialized.

:on-before-plugin-load (fn [CefRequestContextHandler,CefStringUtf16,CefStringUtf16,int,CefStringUtf16,CefWebPluginInfo,int]) -> int
Called on multiple browser process threads before a plugin instance is
loaded. |mime_type| is the mime type of the plugin that will be loaded.
|plugin_url| is the content URL that the plugin will load and may be NULL.
|is_main_frame| will be true (1) if the plugin is being loaded in the main
(top-level) frame, |top_origin_url| is the URL for the top-level frame that
contains the plugin when loading a specific plugin instance or NULL when
building the initial list of enabled plugins for 'navigator.plugins'
JavaScript state. |plugin_info| includes additional information about the
plugin that will be loaded. |plugin_policy| is the recommended policy.
Modify |plugin_policy| and return true (1) to change the policy. Return
false (0) to use the recommended policy. The default plugin policy can be
set at runtime using the `--plugin-policy=[allow|detect|block]` command-
line flag. Decisions to mark a plugin as disabled by setting
|plugin_policy| to PLUGIN_POLICY_DISABLED may be cached when
|top_origin_url| is NULL. To purge the plugin list cache and potentially
trigger new calls to this function call
cef_request_context_t::PurgePluginListCache.

:get-resource-request-handler (fn [CefRequestContextHandler,CefBrowser,CefFrame,CefRequest,int,int,CefStringUtf16,Pointer]) -> CefResourceRequestHandler
Called on the browser process IO thread before a resource request is
initiated. The |browser| and |frame| values represent the source of the
request, and may be NULL for requests originating from service workers or
cef_urlrequest_t. |request| represents the request contents and cannot be
modified in this callback. |is_navigation| will be true (1) if the resource
request is a navigation. |is_download| will be true (1) if the resource
request is a download. |request_initiator| is the origin (scheme + domain)
of the page that initiated the request. Set |disable_default_handling| to
true (1) to disable default handling of the request, in which case it will
need to be handled via cef_resource_request_handler_t::GetResourceHandler
or it will be canceled. To allow the resource load to proceed with default
handling return NULL. To specify a handler for the resource return a
cef_resource_request_handler_t object. This function will not be called if
the client associated with |browser| returns a non-NULL value from
cef_request_handler_t::GetResourceRequestHandler for the same request
(identified by cef_request_t::GetIdentifier).

Make a CefRequestContextSettings
Request context initialization settings. Specify NULL or 0 to get the
recommended default values.

:size size_t
Size of this structure.

:cache-path cef_string_t
The location where cache data for this request context will be stored on
disk. If this value is non-empty then it must be an absolute path that is
either equal to or a child directory of CefSettings.root_cache_path. If
this value is empty then browsers will be created in "incognito mode" where
in-memory caches are used for storage and no data is persisted to disk.
HTML5 databases such as localStorage will only persist across sessions if a
cache path is specified. To share the global browser cache and related
configuration set this value to match the CefSettings.cache_path value.

:persist-session-cookies int
To persist session cookies (cookies without an expiry date or validity
interval) by default when using the global cookie manager set this value to
true (1). Session cookies are generally intended to be transient and most
Web browsers do not persist them. Can be set globally using the
CefSettings.persist_session_cookies value. This value will be ignored if
|cache_path| is empty or if it matches the CefSettings.cache_path value.

:persist-user-preferences int
To persist user preferences as a JSON file in the cache path directory set
this value to true (1). Can be set globally using the
CefSettings.persist_user_preferences value. This value will be ignored if
|cache_path| is empty or if it matches the CefSettings.cache_path value.

:ignore-certificate-errors int
Set to true (1) to ignore errors related to invalid SSL certificates.
Enabling this setting can lead to potential security vulnerabilities like
"man in the middle" attacks. Applications that load content from the
internet should not enable this setting. Can be set globally using the
CefSettings.ignore_certificate_errors value. This value will be ignored if
|cache_path| matches the CefSettings.cache_path value.

:accept-language-list cef_string_t
Comma delimited ordered list of language codes without any whitespace that
will be used in the "Accept-Language" HTTP header. Can be set globally
using the CefSettings.accept_language_list value or overridden on a per-
browser basis using the CefBrowserSettings.accept_language_list value. If
all values are empty then "en-US,en" will be used. This value will be
ignored if |cache_path| matches the CefSettings.cache_path value.

Make a CefRequestHandler
Implement this structure to handle events related to browser requests. The
functions of this structure will be called on the thread indicated.

:on-before-browse (fn [CefRequestHandler,CefBrowser,CefFrame,CefRequest,int,int]) -> int
Called on the UI thread before browser navigation. Return true (1) to
cancel the navigation or false (0) to allow the navigation to proceed. The
|request| object cannot be modified in this callback.
cef_load_handler_t::OnLoadingStateChange will be called twice in all cases.
If the navigation is allowed cef_load_handler_t::OnLoadStart and
cef_load_handler_t::OnLoadEnd will be called. If the navigation is canceled
cef_load_handler_t::OnLoadError will be called with an |errorCode| value of
ERR_ABORTED. The |user_gesture| value will be true (1) if the browser
navigated via explicit user gesture (e.g. clicking a link) or false (0) if
it navigated automatically (e.g. via the DomContentLoaded event).

:on-open-urlfrom-tab (fn [CefRequestHandler,CefBrowser,CefFrame,CefStringUtf16,int,int]) -> int
Called on the UI thread before OnBeforeBrowse in certain limited cases
where navigating a new or different browser might be desirable. This
includes user-initiated navigation that might open in a special way (e.g.
links clicked via middle-click or ctrl + left-click) and certain types of
cross-origin navigation initiated from the renderer process (e.g.
navigating the top-level frame to/from a file URL). The |browser| and
|frame| values represent the source of the navigation. The
|target_disposition| value indicates where the user intended to navigate
the browser based on standard Chromium behaviors (e.g. current tab, new
tab, etc). The |user_gesture| value will be true (1) if the browser
navigated via explicit user gesture (e.g. clicking a link) or false (0) if
it navigated automatically (e.g. via the DomContentLoaded event). Return
true (1) to cancel the navigation or false (0) to allow the navigation to
proceed in the source browser's top-level frame.

:get-resource-request-handler (fn [CefRequestHandler,CefBrowser,CefFrame,CefRequest,int,int,CefStringUtf16,Pointer]) -> CefResourceRequestHandler
Called on the browser process IO thread before a resource request is
initiated. The |browser| and |frame| values represent the source of the
request. |request| represents the request contents and cannot be modified
in this callback. |is_navigation| will be true (1) if the resource request
is a navigation. |is_download| will be true (1) if the resource request is
a download. |request_initiator| is the origin (scheme + domain) of the page
that initiated the request. Set |disable_default_handling| to true (1) to
disable default handling of the request, in which case it will need to be
handled via cef_resource_request_handler_t::GetResourceHandler or it will
be canceled. To allow the resource load to proceed with default handling
return NULL. To specify a handler for the resource return a
cef_resource_request_handler_t object. If this callback returns NULL the
same function will be called on the associated
cef_request_context_handler_t, if any.

:get-auth-credentials (fn [CefRequestHandler,CefBrowser,CefStringUtf16,int,CefStringUtf16,int,CefStringUtf16,CefStringUtf16,CefAuthCallback]) -> int
Called on the IO thread when the browser needs credentials from the user.
|origin_url| is the origin making this authentication request. |isProxy|
indicates whether the host is a proxy server. |host| contains the hostname
and |port| contains the port number. |realm| is the realm of the challenge
and may be NULL. |scheme| is the authentication scheme used, such as
"basic" or "digest", and will be NULL if the source of the request is an
FTP server. Return true (1) to continue the request and call
cef_auth_callback_t::cont() either in this function or at a later time when
the authentication information is available. Return false (0) to cancel the
request immediately.

:on-quota-request (fn [CefRequestHandler,CefBrowser,CefStringUtf16,long,CefRequestCallback]) -> int
Called on the IO thread when JavaScript requests a specific storage quota
size via the webkitStorageInfo.requestQuota function. |origin_url| is the
origin of the page making the request. |new_size| is the requested quota
size in bytes. Return true (1) to continue the request and call
cef_request_callback_t::cont() either in this function or at a later time
to grant or deny the request. Return false (0) to cancel the request
immediately.

:on-certificate-error (fn [CefRequestHandler,CefBrowser,int,CefStringUtf16,CefSslinfo,CefRequestCallback]) -> int
Called on the UI thread to handle requests for URLs with an invalid SSL
certificate. Return true (1) and call cef_request_callback_t::cont() either
in this function or at a later time to continue or cancel the request.
Return false (0) to cancel the request immediately. If
CefSettings.ignore_certificate_errors is set all invalid certificates will
be accepted without calling this function.

:on-select-client-certificate (fn [CefRequestHandler,CefBrowser,int,CefStringUtf16,int,SizeT,Pointer,CefSelectClientCertificateCallback]) -> int
Called on the UI thread when a client certificate is being requested for
authentication. Return false (0) to use the default behavior and
automatically select the first certificate available. Return true (1) and
call cef_select_client_certificate_callback_t::Select either in this
function or at a later time to select a certificate. Do not call Select or
call it with NULL to continue without using any certificate. |isProxy|
indicates whether the host is an HTTPS proxy or the origin server. |host|
and |port| contains the hostname and port of the SSL server. |certificates|
is the list of certificates to choose from; this list has already been
pruned by Chromium so that it only contains certificates from issuers that
the server trusts.

:on-plugin-crashed (fn [CefRequestHandler,CefBrowser,CefStringUtf16]) -> void
Called on the browser process UI thread when a plugin has crashed.
|plugin_path| is the path of the plugin that crashed.

:on-render-view-ready (fn [CefRequestHandler,CefBrowser]) -> void
Called on the browser process UI thread when the render view associated
with |browser| is ready to receive/handle IPC messages in the render
process.

:on-render-process-terminated (fn [CefRequestHandler,CefBrowser,int]) -> void
Called on the browser process UI thread when the render process terminates
unexpectedly. |status| indicates how the process terminated.

:on-document-available-in-main-frame (fn [CefRequestHandler,CefBrowser]) -> void

the main frame has been created.

Make a CefResolveCallback
Callback structure for cef_request_context_t::ResolveHost.

:on-resolve-completed (fn [CefResolveCallback,int,Pointer]) -> void
Called on the UI thread after the ResolveHost request has completed.
|result| will be the result code. |resolved_ips| will be the list of
resolved IP addresses or NULL if the resolution failed.

Make a CefResourceBundleHandler
Structure used to implement a custom resource bundle structure. See
CefSettings for additional options related to resource bundle loading. The
functions of this structure may be called on multiple threads.

:get-localized-string (fn [CefResourceBundleHandler,int,CefStringUtf16]) -> int
Called to retrieve a localized translation for the specified |string_id|.
To provide the translation set |string| to the translation string and
return true (1). To use the default translation return false (0). Include
cef_pack_strings.h for a listing of valid string ID values.

:get-data-resource (fn [CefResourceBundleHandler,int,Pointer,Pointer]) -> int
Called to retrieve data for the specified scale independent |resource_id|.
To provide the resource data set |data| and |data_size| to the data pointer
and size respectively and return true (1). To use the default resource data
return false (0). The resource data will not be copied and must remain
resident in memory. Include cef_pack_resources.h for a listing of valid
resource ID values.

:get-data-resource-for-scale (fn [CefResourceBundleHandler,int,int,Pointer,Pointer]) -> int
Called to retrieve data for the specified |resource_id| nearest the scale
factor |scale_factor|. To provide the resource data set |data| and
|data_size| to the data pointer and size respectively and return true (1).
To use the default resource data return false (0). The resource data will
not be copied and must remain resident in memory. Include
cef_pack_resources.h for a listing of valid resource ID values.

Make a CefResourceHandler
Structure used to implement a custom request handler structure. The functions
of this structure will be called on the IO thread unless otherwise indicated.

:open (fn [CefResourceHandler,CefRequest,Pointer,CefCallback]) -> int
Open the response stream. To handle the request immediately set
|handle_request| to true (1) and return true (1). To decide at a later time
set |handle_request| to false (0), return true (1), and execute |callback|
to continue or cancel the request. To cancel the request immediately set
|handle_request| to true (1) and return false (0). This function will be
called in sequence but not from a dedicated thread. For backwards
compatibility set |handle_request| to false (0) and return false (0) and
the ProcessRequest function will be called.

:process-request (fn [CefResourceHandler,CefRequest,CefCallback]) -> int
Begin processing the request. To handle the request return true (1) and
call cef_callback_t::cont() once the response header information is
available (cef_callback_t::cont() can also be called from inside this
function if header information is available immediately). To cancel the
request return false (0).
WARNING: This function is deprecated. Use Open instead.

:get-response-headers (fn [CefResourceHandler,CefResponse,Pointer,CefStringUtf16]) -> void
Retrieve response header information. If the response length is not known
set |response_length| to -1 and read_response() will be called until it
returns false (0). If the response length is known set |response_length| to
a positive value and read_response() will be called until it returns false
(0) or the specified number of bytes have been read. Use the |response|
object to set the mime type, http status code and other optional header
values. To redirect the request to a new URL set |redirectUrl| to the new
URL. |redirectUrl| can be either a relative or fully qualified URL. It is
also possible to set |response| to a redirect http status code and pass the
new URL via a Location header. Likewise with |redirectUrl| it is valid to
set a relative or fully qualified URL as the Location header value. If an
error occured while setting up the request you can call set_error() on
|response| to indicate the error condition.

:skip (fn [CefResourceHandler,long,Pointer,CefResourceSkipCallback]) -> int
Skip response data when requested by a Range header. Skip over and discard
|bytes_to_skip| bytes of response data. If data is available immediately
set |bytes_skipped| to the number of bytes skipped and return true (1). To
read the data at a later time set |bytes_skipped| to 0, return true (1) and
execute |callback| when the data is available. To indicate failure set
|bytes_skipped| to < 0 (e.g. -2 for ERR_FAILED) and return false (0). This
function will be called in sequence but not from a dedicated thread.

:read (fn [CefResourceHandler,Pointer,int,Pointer,CefResourceReadCallback]) -> int
Read response data. If data is available immediately copy up to
|bytes_to_read| bytes into |data_out|, set |bytes_read| to the number of
bytes copied, and return true (1). To read the data at a later time keep a
pointer to |data_out|, set |bytes_read| to 0, return true (1) and execute
|callback| when the data is available (|data_out| will remain valid until
the callback is executed). To indicate response completion set |bytes_read|
to 0 and return false (0). To indicate failure set |bytes_read| to < 0
(e.g. -2 for ERR_FAILED) and return false (0). This function will be called
in sequence but not from a dedicated thread. For backwards compatibility
set |bytes_read| to -1 and return false (0) and the ReadResponse function
will be called.

:read-response (fn [CefResourceHandler,Pointer,int,Pointer,CefCallback]) -> int
Read response data. If data is available immediately copy up to
|bytes_to_read| bytes into |data_out|, set |bytes_read| to the number of
bytes copied, and return true (1). To read the data at a later time set
|bytes_read| to 0, return true (1) and call cef_callback_t::cont() when the
data is available. To indicate response completion return false (0).
WARNING: This function is deprecated. Use Skip and Read instead.

:cancel (fn [CefResourceHandler]) -> void
Request processing has been canceled.

Make a CefResourceReadCallback
Callback for asynchronous continuation of cef_resource_handler_t::read().

:cont (fn [CefResourceReadCallback,int]) -> void
Callback for asynchronous continuation of read(). If |bytes_read| == 0 the
response will be considered complete. If |bytes_read| > 0 then read() will
be called again until the request is complete (based on either the result
or the expected content length). If |bytes_read| < 0 then the request will
fail and the |bytes_read| value will be treated as the error code.

Make a CefResourceRequestHandler
Implement this structure to handle events related to browser requests. The
functions of this structure will be called on the IO thread unless otherwise
indicated.

:get-cookie-access-filter (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest]) -> CefCookieAccessFilter

modified in this callback.

:on-before-resource-load (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefRequestCallback]) -> int
Called on the IO thread before a resource request is loaded. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. To redirect
or change the resource load optionally modify |request|. Modification of
the request URL will be treated as a redirect. Return RV_CONTINUE to
continue the request immediately. Return RV_CONTINUE_ASYNC and call
cef_request_callback_t:: cont() at a later time to continue or cancel the
request asynchronously. Return RV_CANCEL to cancel the request immediately.

:get-resource-handler (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest]) -> CefResourceHandler
Called on the IO thread before a resource is loaded. The |browser| and
|frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. To allow the
resource to load using the default network loader return NULL. To specify a
handler for the resource return a cef_resource_handler_t object. The
|request| object cannot not be modified in this callback.

:on-resource-redirect (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse,CefStringUtf16]) -> void
Called on the IO thread when a resource load is redirected. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. The
|request| parameter will contain the old URL and other request-related
information. The |response| parameter will contain the response that
resulted in the redirect. The |new_url| parameter will contain the new URL
and can be changed if desired. The |request| and |response| objects cannot
be modified in this callback.

:on-resource-response (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse]) -> int
Called on the IO thread when a resource response is received. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. To allow the
resource load to proceed without modification return false (0). To redirect
or retry the resource load optionally modify |request| and return true (1).
Modification of the request URL will be treated as a redirect. Requests
handled using the default network loader cannot be redirected in this
callback. The |response| object cannot be modified in this callback.
WARNING: Redirecting using this function is deprecated. Use
OnBeforeResourceLoad or GetResourceHandler to perform redirects.

:get-resource-response-filter (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse]) -> CefResponseFilter
Called on the IO thread to optionally filter resource response content. The
|browser| and |frame| values represent the source of the request, and may
be NULL for requests originating from service workers or cef_urlrequest_t.
|request| and |response| represent the request and response respectively
and cannot be modified in this callback.

:on-resource-load-complete (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse,int,long]) -> void
Called on the IO thread when a resource load has completed. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. |request|
and |response| represent the request and response respectively and cannot
be modified in this callback. |status| indicates the load completion
status. |received_content_length| is the number of response bytes actually
read. This function will be called for all requests, including requests
that are aborted due to CEF shutdown or destruction of the associated
browser. In cases where the associated browser is destroyed this callback
may arrive after the cef_life_span_handler_t::OnBeforeClose callback for
that browser. The cef_frame_t::IsValid function can be used to test for
this situation, and care should be taken not to call |browser| or |frame|
functions that modify state (like LoadURL, SendProcessMessage, etc.) if the
frame is invalid.

:on-protocol-execution (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,Pointer]) -> void
Called on the IO thread to handle requests for URLs with an unknown
protocol component. The |browser| and |frame| values represent the source
of the request, and may be NULL for requests originating from service
workers or cef_urlrequest_t. |request| cannot be modified in this callback.
Set |allow_os_execution| to true (1) to attempt execution via the
registered OS protocol handler, if any. SECURITY WARNING: YOU SHOULD USE
THIS METHOD TO ENFORCE RESTRICTIONS BASED ON SCHEME, HOST OR OTHER URL
ANALYSIS BEFORE ALLOWING OS EXECUTION.

Make a CefResourceSkipCallback
Callback for asynchronous continuation of cef_resource_handler_t::skip().

:cont (fn [CefResourceSkipCallback,long]) -> void
Callback for asynchronous continuation of skip(). If |bytes_skipped| > 0
then either skip() will be called again until the requested number of bytes
have been skipped or the request will proceed. If |bytes_skipped| <= 0 the

Get the response status code.

:set-status (fn [CefResponse,int]) -> void
Set the response status code.

:get-status-text (fn [CefResponse]) -> CefStringUtf16

Make a CefResponseFilter
Implement this structure to filter resource response content. The functions
of this structure will be called on the browser process IO thread.

:init-filter (fn [CefResponseFilter]) -> int
Initialize the response filter. Will only be called a single time. The
filter will not be installed if this function returns false (0).

:filter (fn [CefResponseFilter,Pointer,SizeT,Pointer,Pointer,SizeT,Pointer]) -> int
Called to filter a chunk of data. Expected usage is as follows:
A. Read input data from |data_in| and set |data_in_read| to the number of
bytes that were read up to a maximum of |data_in_size|. |data_in| will
be NULL if |data_in_size| is zero.
B. Write filtered output data to |data_out| and set |data_out_written| to
the number of bytes that were written up to a maximum of
|data_out_size|. If no output data was written then all data must be
read from |data_in| (user must set |data_in_read| = |data_in_size|).
C. Return RESPONSE_FILTER_DONE if all output data was written or
RESPONSE_FILTER_NEED_MORE_DATA if output data is still pending.
This function will be called repeatedly until the input buffer has been
fully read (user sets |data_in_read| = |data_in_size|) and there is no more
input data to filter (the resource response is complete). This function may
then be called an additional time with an NULL input buffer if the user
filled the output buffer (set |data_out_written| = |data_out_size|) and
returned RESPONSE_FILTER_NEED_MORE_DATA to indicate that output data is
still pending.
Calls to this function will stop when one of the following conditions is
met:
A. There is no more input data to filter (the resource response is
complete) and the user sets |data_out_written| = 0 or returns
RESPONSE_FILTER_DONE to indicate that all data has been written, or;
B. The user returns RESPONSE_FILTER_ERROR to indicate an error.
Do not keep a reference to the buffers passed to this function.

Called asynchronously after the file dialog is dismissed.
|selected_accept_filter| is the 0-based index of the value selected from
the accept filters array passed to cef_browser_host_t::RunFileDialog.
|file_paths| will be a single value or a list of values depending on the
dialog mode. If the selection was cancelled |file_paths| will be NULL.

Make a CefSchemeHandlerFactory
Structure that creates cef_resource_handler_t instances for handling scheme
requests. The functions of this structure will always be called on the IO
thread.

:create (fn [CefSchemeHandlerFactory,CefBrowser,CefFrame,CefStringUtf16,CefRequest]) -> CefResourceHandler
Return a new resource handler instance to handle the request or an NULL
reference to allow default handling of the request. |browser| and |frame|
will be the browser window and frame respectively that originated the

scheduling via the CefBrowserProcessHandler::OnScheduleMessagePumpWork()
callback. This option is recommended for use in combination with the
CefDoMessageLoopWork() function in cases where the CEF message loop must be
integrated into an existing application message loop (see additional
comments and warnings on CefDoMessageLoopWork). Enabling this option is not
recommended for most users; leave this option disabled and use either the
CefRunMessageLoop() function or multi_threaded_message_loop if possible.

:windowless-rendering-enabled int

is the name of the main app executable. Also configurable using the
"log-file" command-line switch.

:log-severity cef_log_severity_t
The log severity. Only messages of this severity level or higher will be
logged. When set to DISABLE no messages will be written to the log file,
but FATAL messages will still be output to stderr. Also configurable using

providing an appropriate |dtor| implementation that will free the string in
the same memory space. When reusing an existing string structure make sure
to call |dtor| for the old value before assigning new |str| and |dtor|
values. Static strings will have a NULL |dtor| value. Using the below
functions if you want this managed for you.

Make a CefTask
Implement this structure for asynchronous task execution. If the task is
posted successfully and if the associated message loop is still running then
the execute() function will be called on the target thread. If the task fails
to post then the task object may be destroyed on the source thread instead of
the target thread. For this reason be cautious when performing work in the
task object destructor.

:execute (fn [CefTask]) -> void
Method that will be executed on the target thread.

Make a CefTaskRunner

|isProxy| indicates whether the host is a proxy server. |host| contains the
hostname and |port| contains the port number. Return true (1) to continue
the request and call cef_auth_callback_t::cont() when the authentication
information is available. If the request has an associated browser/frame
then returning false (0) will result in a call to GetAuthCredentials on the
cef_request_handler_t associated with that browser, if any. Otherwise,
returning false (0) will cancel the request immediately. This function will
only be called for requests initiated from the browser process.

Make a CefV8accessor

object passed to this function. The CefSettings.command_line_args_disabled
value can be used to start with an NULL command-line object. Any values
specified in CefSettings that equate to command-line arguments will be set
before this function is called. Be cautious when using this function to
modify command-line arguments for non-browser processes as this may result
in undefined behavior including crashes.

:on-register-custom-schemes (fn [CefApp,CefSchemeRegistrar]) -> void
Provides an opportunity to register custom schemes. Do not keep a reference
to the |registrar| object. This function is called on the main thread for
each process and the registered schemes should be the same across all
processes.

:get-resource-bundle-handler (fn [CefApp]) -> CefResourceBundleHandler
Return the handler for resource bundle events. If
CefSettings.pack_loading_disabled is true (1) a handler must be returned.
If no handler is returned resources will be loaded from pack files. This
function is called by the browser and render processes on multiple threads.

:get-browser-process-handler (fn [CefApp]) -> CefBrowserProcessHandler
Return the handler for functionality specific to the browser process. This
function is called on multiple threads in the browser process.

:get-render-process-handler (fn [CefApp]) -> CefRenderProcessHandler
Return the handler for functionality specific to the render process. This
function is called on the render process main thread.

Merge properties of a CefAudioHandler
Implement this structure to handle audio events.

:get-audio-parameters (fn [CefAudioHandler,CefBrowser,CefAudioParameters]) -> int
Called on the UI thread to allow configuration of audio stream parameters.

cancel it. All members of |params| can optionally be configured here, but
they are also pre-filled with some sensible defaults.

:on-audio-stream-started (fn [CefAudioHandler,CefBrowser,CefAudioParameters,int]) -> void
Called on a browser audio capture thread when the browser starts streaming
audio. OnAudioSteamStopped will always be called after
OnAudioStreamStarted; both functions may be called multiple times for the
same browser. |params| contains the audio parameters like sample rate and
channel layout. |channels| is the number of channels.

:on-audio-stream-packet (fn [CefAudioHandler,CefBrowser,Pointer,int,long]) -> void
Called on the audio stream thread when a PCM packet is received for the
stream. |data| is an array representing the raw PCM data as a floating
point type, i.e. 4-byte value(s). |frames| is the number of frames in the
PCM packet. |pts| is the presentation timestamp (in milliseconds since the
Unix Epoch) and represents the time at which the decompressed packet should
be presented to the user. Based on |frames| and the |channel_layout| value
passed to OnAudioStreamStarted you can calculate the size of the |data|
array in bytes.

:on-audio-stream-stopped (fn [CefAudioHandler,CefBrowser]) -> void
Called on the UI thread when the stream has stopped. OnAudioSteamStopped
will always be called after OnAudioStreamStarted; both functions may be
called multiple times for the same stream.

:on-audio-stream-error (fn [CefAudioHandler,CefBrowser,CefStringUtf16]) -> void
Called on the UI or audio stream thread when an error occurred. During the
stream creation phase this callback will be called on the UI thread while
in the capturing phase it will be called on the audio stream thread. The
stream will be stopped immediately.

Merge properties of a CefBinaryValue
Structure representing a binary value. Can be used on any process and thread.

:is-valid (fn [CefBinaryValue]) -> int
Returns true (1) if this object is valid. This object may become invalid if
the underlying data is owned by another object (e.g. list or dictionary)

:default-flex int
Default flex for views when none is specified via CefBoxLayout methods.
Using the preferred size as the basis, free space along the main axis is
distributed to views in the ratio of their flex weights. Similarly, if the
views will overflow the parent, space is subtracted in these ratios. A flex
of 0 means this view is not resized. Flex values must not be negative.

Merge properties of a CefBrowser
Structure used to represent a browser window. When used in the browser
process the functions of this structure may be called on any thread unless
otherwise indicated in the comments. When used in the render process the
functions of this structure may only be called on the main thread.

in the comments.

:get-browser (fn [CefBrowserHost]) -> CefBrowser
Returns the hosted browser object.

:close-browser (fn [CefBrowserHost,int]) -> void
Request that the browser close. The JavaScript 'onbeforeunload' event will
be fired. If |force_close| is false (0) the event handler, if any, will be
allowed to prompt the user and the user can optionally cancel the close. If
|force_close| is true (1) the prompt will not be displayed and the close
will proceed. Results in a call to cef_life_span_handler_t::do_close() if
the event handler allows the close or if |force_close| is true (1). See
cef_life_span_handler_t::do_close() documentation for additional usage
information.

:try-close-browser (fn [CefBrowserHost]) -> int
Helper for closing a browser. Call this function from the top-level window
close handler. Internally this calls CloseBrowser(false (0)) if the close
has not yet been initiated. This function returns false (0) while the close
is pending and true (1) after the close has completed. See close_browser()
and cef_life_span_handler_t::do_close() documentation for additional usage
information. This function must be called on the browser process UI thread.

can only be called on the UI thread.

:set-zoom-level (fn [CefBrowserHost,double]) -> void
Change the zoom level to the specified value. Specify 0.0 to reset the zoom
level. If called on the UI thread the change will be applied immediately.
Otherwise, the change will be applied asynchronously on the UI thread.

:run-file-dialog (fn [CefBrowserHost,int,CefStringUtf16,CefStringUtf16,Pointer,int,CefRunFileDialogCallback]) -> void
Call to run a file chooser dialog. Only a single file chooser dialog may be
pending at any given time. |mode| represents the type of dialog to display.
|title| to the title to be used for the dialog and may be NULL to show the
default title ("Open" or "Save" depending on the mode). |default_file_path|
is the path with optional directory and/or file name component that will be
initially selected in the dialog. |accept_filters| are used to restrict the
selectable file types and may any combination of (a) valid lower-cased MIME
types (e.g. "text/*" or "image/*"), (b) individual file extensions (e.g.
".txt" or ".png"), or (c) combined description and file extension delimited
using "|" and ";" (e.g. "Image Types|.png;.gif;.jpg").
|selected_accept_filter| is the 0-based index of the filter that will be
selected by default. |callback| will be executed after the dialog is
dismissed or immediately if another dialog is already pending. The dialog
will be initiated asynchronously on the UI thread.

:start-download (fn [CefBrowserHost,CefStringUtf16]) -> void
Download the file at |url| using cef_download_handler_t.

:download-image (fn [CefBrowserHost,CefStringUtf16,int,int,int,CefDownloadImageCallback]) -> void
Download |image_url| and execute |callback| on completion with the images
received from the renderer. If |is_favicon| is true (1) then cookies are
not sent and not accepted during download. Images with density independent
pixel (DIP) sizes larger than |max_image_size| are filtered out from the
image results. Versions of the image at different scale factors may be
downloaded up to the maximum scale factor supported by the system. If there
are no image results <= |max_image_size| then the smallest image is resized
to |max_image_size| and is the only result. A |max_image_size| of 0 means
unlimited. If |bypass_cache| is true (1) then |image_url| is requested from
the server even if it is present in the browser cache.

:print (fn [CefBrowserHost]) -> void
Print the current browser contents.

:print-to-pdf (fn [CefBrowserHost,CefStringUtf16,CefPdfPrintSettings,CefPdfPrintCallback]) -> void
Print the current browser contents to the PDF file specified by |path| and
execute |callback| on completion. The caller is responsible for deleting
|path| when done. For PDF printing to work on Linux you must implement the
cef_print_handler_t::GetPdfPaperSize function.

:find (fn [CefBrowserHost,int,CefStringUtf16,int,int,int]) -> void
Search for |searchText|. |identifier| must be a unique ID and these IDs
must strictly increase so that newer requests always have greater IDs than
older requests. If |identifier| is zero or less than the previous ID value
then it will be automatically assigned a new valid ID. |forward| indicates
whether to search forward or backward within the page. |matchCase|
indicates whether the search should be case-sensitive. |findNext| indicates
whether this is the first request or a follow-up. The cef_find_handler_t
instance, if any, returned via cef_client_t::GetFindHandler will be called
to report find results.

:stop-finding (fn [CefBrowserHost,int]) -> void
Cancel all searches that are currently going on.

:show-dev-tools (fn [CefBrowserHost,Pointer,CefClient,CefBrowserSettings,CefPoint]) -> void
Open developer tools (DevTools) in its own browser. The DevTools browser
will remain associated with this browser. If the DevTools browser is
already open then it will be focused, in which case the |windowInfo|,
|client| and |settings| parameters will be ignored. If |inspect_element_at|
is non-NULL then the element at the specified (x,y) location will be
inspected. The |windowInfo| parameter will be ignored if this browser is
wrapped in a cef_browser_view_t.

:close-dev-tools (fn [CefBrowserHost]) -> void
Explicitly close the associated DevTools browser, if any.

:has-dev-tools (fn [CefBrowserHost]) -> int
Returns true (1) if this browser currently has an associated DevTools
browser. Must be called on the browser process UI thread.

:send-dev-tools-message (fn [CefBrowserHost,Pointer,SizeT]) -> int
Send a function call message over the DevTools protocol. |message| must be
a UTF8-encoded JSON dictionary that contains "id" (int), "function"
(string) and "params" (dictionary, optional) values. See the DevTools
protocol documentation at https://chromedevtools.github.io/devtools-
protocol/ for details of supported functions and the expected "params"
dictionary contents. |message| will be copied if necessary. This function
will return true (1) if called on the UI thread and the message was
successfully submitted for validation, otherwise false (0). Validation will
be applied asynchronously and any messages that fail due to formatting
errors or missing parameters may be discarded without notification. Prefer
ExecuteDevToolsMethod if a more structured approach to message formatting
is desired.
Every valid function call will result in an asynchronous function result or
error message that references the sent message "id". Event messages are
received while notifications are enabled (for example, between function
calls for "Page.enable" and "Page.disable"). All received messages will be
delivered to the observer(s) registered with AddDevToolsMessageObserver.
See cef_dev_tools_message_observer_t::OnDevToolsMessage documentation for
details of received message contents.
Usage of the SendDevToolsMessage, ExecuteDevToolsMethod and
AddDevToolsMessageObserver functions does not require an active DevTools
front-end or remote-debugging session. Other active DevTools sessions will
continue to function independently. However, any modification of global
browser state by one session may not be reflected in the UI of other
sessions.
Communication with the DevTools front-end (when displayed) can be logged
for development purposes by passing the `--devtools-protocol-log-
file=<path>` command-line flag.

:execute-dev-tools-method (fn [CefBrowserHost,int,CefStringUtf16,CefDictionaryValue]) -> int
Execute a function call over the DevTools protocol. This is a more
structured version of SendDevToolsMessage. |message_id| is an incremental
number that uniquely identifies the message (pass 0 to have the next number
assigned automatically based on previous values). |function| is the
function name. |params| are the function parameters, which may be NULL. See
the DevTools protocol documentation (linked above) for details of supported
functions and the expected |params| dictionary contents. This function will
return the assigned message ID if called on the UI thread and the message
was successfully submitted for validation, otherwise 0. See the
SendDevToolsMessage documentation for additional usage information.

:add-dev-tools-message-observer (fn [CefBrowserHost,CefDevToolsMessageObserver]) -> CefRegistration
Add an observer for DevTools protocol messages (function results and
events). The observer will remain registered until the returned
Registration object is destroyed. See the SendDevToolsMessage documentation
for additional usage information.

:get-navigation-entries (fn [CefBrowserHost,CefNavigationEntryVisitor,int]) -> void
Retrieve a snapshot of current navigation entries as values sent to the
specified visitor. If |current_only| is true (1) only the current
navigation entry will be sent, otherwise all navigation entries will be
sent.

:replace-misspelling (fn [CefBrowserHost,CefStringUtf16]) -> void
If a misspelled word is currently selected in an editable node calling this
function will replace it with the specified |word|.

:add-word-to-dictionary (fn [CefBrowserHost,CefStringUtf16]) -> void
Add the specified |word| to the spelling dictionary.

:is-window-rendering-disabled (fn [CefBrowserHost]) -> int
Returns true (1) if window rendering is disabled.

:was-resized (fn [CefBrowserHost]) -> void
Notify the browser that the widget has been resized. The browser will first
call cef_render_handler_t::GetViewRect to get the new size and then call
cef_render_handler_t::OnPaint asynchronously with the updated regions. This
function is only used when window rendering is disabled.

:was-hidden (fn [CefBrowserHost,int]) -> void
Notify the browser that it has been hidden or shown. Layouting and
cef_render_handler_t::OnPaint notification will stop when the browser is
hidden. This function is only used when window rendering is disabled.

:notify-screen-info-changed (fn [CefBrowserHost]) -> void
Send a notification to the browser that the screen info has changed. The
browser will then call cef_render_handler_t::GetScreenInfo to update the
screen information with the new values. This simulates moving the webview
window from one display to another, or changing the properties of the
current display. This function is only used when window rendering is
disabled.

:invalidate (fn [CefBrowserHost,int]) -> void
Invalidate the view. The browser will call cef_render_handler_t::OnPaint
asynchronously. This function is only used when window rendering is
disabled.

:send-external-begin-frame (fn [CefBrowserHost]) -> void
Issue a BeginFrame request to Chromium.  Only valid when
cef_window_tInfo::external_begin_frame_enabled is set to true (1).

:send-key-event (fn [CefBrowserHost,CefKeyEvent]) -> void
Send a key event to the browser.

:send-mouse-click-event (fn [CefBrowserHost,CefMouseEvent,int,int,int]) -> void
Send a mouse click event to the browser. The |x| and |y| coordinates are
relative to the upper-left corner of the view.

:send-mouse-move-event (fn [CefBrowserHost,CefMouseEvent,int]) -> void

relative to the upper-left corner of the view.

:send-mouse-wheel-event (fn [CefBrowserHost,CefMouseEvent,int,int]) -> void
Send a mouse wheel event to the browser. The |x| and |y| coordinates are
relative to the upper-left corner of the view. The |deltaX| and |deltaY|
values represent the movement delta in the X and Y directions respectively.
In order to scroll inside select popups with window rendering disabled
cef_render_handler_t::GetScreenPoint should be implemented properly.

:send-touch-event (fn [CefBrowserHost,CefTouchEvent]) -> void
Send a touch event to the browser for a windowless browser.

:send-focus-event (fn [CefBrowserHost,int]) -> void
Send a focus event to the browser.

resized. This function is only used on Windows and Linux.

:get-windowless-frame-rate (fn [CefBrowserHost]) -> int
Returns the maximum rate in frames per second (fps) that
cef_render_handler_t:: OnPaint will be called for a windowless browser. The
actual fps may be lower if the browser cannot generate frames at the
requested rate. The minimum value is 1 and the maximum value is 60 (default
30). This function can only be called on the UI thread.

:set-windowless-frame-rate (fn [CefBrowserHost,int]) -> void
Set the maximum rate in frames per second (fps) that cef_render_handler_t::
OnPaint will be called for a windowless browser. The actual fps may be
lower if the browser cannot generate frames at the requested rate. The
minimum value is 1 and the maximum value is 60 (default 30). Can also be
set at browser creation via cef_browser_tSettings.windowless_frame_rate.

:ime-set-composition (fn [CefBrowserHost,CefStringUtf16,SizeT,CefCompositionUnderline,CefRange,CefRange]) -> void
Begins a new composition or updates the existing composition. Blink has a
special node (a composition node) that allows the input function to change
text without affecting other DOM nodes. |text| is the optional text that
will be inserted into the composition node. |underlines| is an optional set
of ranges that will be underlined in the resulting text.
|replacement_range| is an optional range of the existing text that will be
replaced. |selection_range| is an optional range of the resulting text that
will be selected after insertion or replacement. The |replacement_range|
value is only used on OS X.
This function may be called multiple times as the composition changes. When
the client is done making changes the composition should either be canceled
or completed. To cancel the composition call ImeCancelComposition. To
complete the composition call either ImeCommitText or
ImeFinishComposingText. Completion is usually signaled when:
A. The client receives a WM_IME_COMPOSITION message with a GCS_RESULTSTR
flag (on Windows), or;
B. The client receives a "commit" signal of GtkIMContext (on Linux), or;
C. insertText of NSTextInput is called (on Mac).
This function is only used when window rendering is disabled.

:ime-commit-text (fn [CefBrowserHost,CefStringUtf16,CefRange,int]) -> void
Completes the existing composition by optionally inserting the specified
|text| into the composition node. |replacement_range| is an optional range
of the existing text that will be replaced. |relative_cursor_pos| is where
the cursor will be positioned relative to the current cursor position. See
comments on ImeSetComposition for usage. The |replacement_range| and
|relative_cursor_pos| values are only used on OS X. This function is only
used when window rendering is disabled.

:ime-finish-composing-text (fn [CefBrowserHost,int]) -> void
Completes the existing composition by applying the current composition node
contents. If |keep_selection| is false (0) the current selection, if any,
will be discarded. See comments on ImeSetComposition for usage. This
function is only used when window rendering is disabled.

:ime-cancel-composition (fn [CefBrowserHost]) -> void
Cancels the existing composition and discards the composition node contents
without applying them. See comments on ImeSetComposition for usage. This
function is only used when window rendering is disabled.

:drag-target-drag-enter (fn [CefBrowserHost,CefDragData,CefMouseEvent,int]) -> void
Call this function when the user drags the mouse into the web view (before
calling DragTargetDragOver/DragTargetLeave/DragTargetDrop). |drag_data|
should not contain file contents as this type of data is not allowed to be
dragged into the web view. File contents can be removed using
cef_drag_data_t::ResetFileContents (for example, if |drag_data| comes from
cef_render_handler_t::StartDragging). This function is only used when
window rendering is disabled.

:drag-target-drag-over (fn [CefBrowserHost,CefMouseEvent,int]) -> void
Call this function each time the mouse is moved across the web view during
a drag operation (after calling DragTargetDragEnter and before calling
DragTargetDragLeave/DragTargetDrop). This function is only used when window
rendering is disabled.

:drag-target-drag-leave (fn [CefBrowserHost]) -> void
Call this function when the user drags the mouse out of the web view (after
calling DragTargetDragEnter). This function is only used when window
rendering is disabled.

:drag-target-drop (fn [CefBrowserHost,CefMouseEvent]) -> void
Call this function when the user completes the drag operation by dropping
the object onto the web view (after calling DragTargetDragEnter). The
object being dropped is |drag_data|, given as an argument to the previous
DragTargetDragEnter call. This function is only used when window rendering
is disabled.

:drag-source-ended-at (fn [CefBrowserHost,int,int,int]) -> void
Call this function when the drag operation started by a
cef_render_handler_t::StartDragging call has ended either in a drop or by
being cancelled. |x| and |y| are mouse coordinates relative to the upper-
left corner of the view. If the web view is both the drag source and the
drag target then all DragTarget* functions should be called before
DragSource* mthods. This function is only used when window rendering is
disabled.

:drag-source-system-drag-ended (fn [CefBrowserHost]) -> void
Call this function when the drag operation started by a
cef_render_handler_t::StartDragging call has completed. This function may
be called immediately without first calling DragSourceEndedAt to cancel a
drag operation. If the web view is both the drag source and the drag target
then all DragTarget* functions should be called before DragSource* mthods.
This function is only used when window rendering is disabled.

:get-visible-navigation-entry (fn [CefBrowserHost]) -> CefNavigationEntry
Returns the current visible navigation entry for this browser. This
function can only be called on the UI thread.

:set-accessibility-state (fn [CefBrowserHost,int]) -> void
Set accessibility state for all frames. |accessibility_state| may be
default, enabled or disabled. If |accessibility_state| is STATE_DEFAULT
then accessibility will be disabled by default and the state may be further
controlled with the "force-renderer-accessibility" and "disable-renderer-
accessibility" command-line switches. If |accessibility_state| is
STATE_ENABLED then accessibility will be enabled. If |accessibility_state|
is STATE_DISABLED then accessibility will be completely disabled.
For windowed browsers accessibility will be enabled in Complete mode (which
corresponds to kAccessibilityModeComplete in Chromium). In this mode all
platform accessibility objects will be created and managed by Chromium's
internal implementation. The client needs only to detect the screen reader
and call this function appropriately. For example, on macOS the client can
handle the @"AXEnhancedUserStructure" accessibility attribute to detect
VoiceOver state changes and on Windows the client can handle WM_GETOBJECT
with OBJID_CLIENT to detect accessibility readers.
For windowless browsers accessibility will be enabled in TreeOnly mode
(which corresponds to kAccessibilityModeWebContentsOnly in Chromium). In
this mode renderer accessibility is enabled, the full tree is computed, and
events are passed to CefAccessibiltyHandler, but platform accessibility
objects are not created. The client may implement platform accessibility
objects using CefAccessibiltyHandler callbacks if desired.

:set-auto-resize-enabled (fn [CefBrowserHost,int,CefSize,CefSize]) -> void
Enable notifications of auto resize via
cef_display_handler_t::OnAutoResize. Notifications are disabled by default.
|min_size| and |max_size| define the range of allowed sizes.

:get-extension (fn [CefBrowserHost]) -> CefExtension
Returns the extension hosted in this browser or NULL if no extension is
hosted. See cef_request_context_t::LoadExtension for details.

:is-background-host (fn [CefBrowserHost]) -> int
Returns true (1) if this browser is hosting an extension background script.

structure will be called on the browser process main thread unless otherwise
indicated.

:get-cookieable-schemes (fn [CefBrowserProcessHandler,Pointer,Pointer]) -> void
Called on the browser process UI thread to retrieve the list of schemes
that should support cookies. If |include_defaults| is true (1) the default
schemes ("http", "https", "ws" and "wss") will also be supported. Providing
an NULL |schemes| value and setting |include_defaults| to false (0) will
disable all loading and saving of cookies.
This state will apply to the cef_cookie_manager_t associated with the
global cef_request_context_t. It will also be used as the initial state for
any new cef_request_context_ts created by the client. After creating a new
cef_request_context_t the cef_cookie_manager_t::SetSupportedSchemes
function may be called on the associated cef_cookie_manager_t to futher
override these values.

main (UI) thread. This callback is used in combination with CefSettings.
external_message_pump and cef_do_message_loop_work() in cases where the CEF
message loop must be integrated into an existing application message loop
(see additional comments and warnings on CefDoMessageLoopWork). This
callback should schedule a cef_do_message_loop_work() call to happen on the
main (UI) thread. |delay_ms| is the requested delay in milliseconds. If
|delay_ms| is <= 0 then the call should happen reasonably soon. If
|delay_ms| is > 0 then the call should be scheduled to happen after the
specified delay and any currently pending scheduled call should be
cancelled.

:get-default-client (fn [CefBrowserProcessHandler]) -> CefClient
Return the default client for use with a newly created browser window. If
null is returned the browser will be unmanaged (no callbacks will be
executed for that browser) and application shutdown will be blocked until
the browser window is closed manually. This function is currently only used
with the chrome runtime.

opaque then the RGB components will be used as the background color. If the
alpha component is fully transparent for a windowed browser then the
CefSettings.background_color value will be used. If the alpha component is
fully transparent for a windowless (off-screen) browser then transparent
painting will be enabled.

:accept-language-list cef_string_t
Comma delimited ordered list of language codes without any whitespace that
will be used in the "Accept-Language" HTTP header. May be set globally
using the CefBrowserSettings.accept_language_list value. If both values are

Returns false (0) if cookies cannot be accessed.

:set-cookie (fn [CefCookieManager,CefStringUtf16,CefCookie,CefSetCookieCallback]) -> int
Sets a cookie given a valid URL and explicit user-provided cookie
attributes. This function expects each attribute to be well-formed. It will
check for disallowed characters (e.g. the ';' character is disallowed
within the cookie value attribute) and fail without setting the cookie if
such characters are found. If |callback| is non-NULL it will be executed
asnychronously on the UI thread after the cookie has been set. Returns
false (0) if an invalid URL is specified or if cookies cannot be accessed.

:delete-cookies (fn [CefCookieManager,CefStringUtf16,CefStringUtf16,CefDeleteCookiesCallback]) -> int

domain cookies) irrespective of path will be deleted. If |url| is NULL all
cookies for all hosts and domains will be deleted. If |callback| is non-
NULL it will be executed asnychronously on the UI thread after the cookies
have been deleted. Returns false (0) if a non-NULL invalid URL is specified
or if cookies cannot be accessed. Cookies can alternately be deleted using
the Visit*Cookies() functions.

:flush-store (fn [CefCookieManager,CefCompletionCallback]) -> int
Flush the backing store (if any) to disk. If |callback| is non-NULL it will
be executed asnychronously on the UI thread after the flush is complete.

OnDevToolsMethodResult or OnDevToolsEvent functions as appropriate.
Method result dictionaries include an "id" (int) value that identifies the
orginating function call sent from cef_browser_host_t::SendDevToolsMessage,
and optionally either a "result" (dictionary) or "error" (dictionary)
value. The "error" dictionary will contain "code" (int) and "message"
(string) values. Event dictionaries include a "function" (string) value and
optionally a "params" (dictionary) value. See the DevTools protocol
documentation at https://chromedevtools.github.io/devtools-protocol/ for

:on-file-dialog (fn [CefDialogHandler,CefBrowser,int,CefStringUtf16,CefStringUtf16,Pointer,int,CefFileDialogCallback]) -> int
Called to run a file chooser dialog. |mode| represents the type of dialog
to display. |title| to the title to be used for the dialog and may be NULL
to show the default title ("Open" or "Save" depending on the mode).
|default_file_path| is the path with optional directory and/or file name
component that should be initially selected in the dialog. |accept_filters|
are used to restrict the selectable file types and may any combination of
(a) valid lower-cased MIME types (e.g. "text/*" or "image/*"), (b)
individual file extensions (e.g. ".txt" or ".png"), or (c) combined
description and file extension delimited using "|" and ";" (e.g. "Image
Types|.png;.gif;.jpg"). |selected_accept_filter| is the 0-based index of
the filter that should be selected by default. To display a custom dialog
return true (1) and execute |callback| either inline or at a later time. To
display the default dialog return false (0).

Merge properties of a CefDictionaryValue
Structure representing a dictionary value. Can be used on any process and
thread.

:is-valid (fn [CefDictionaryValue]) -> int
Returns true (1) if this object is valid. This object may become invalid if
the underlying data is owned by another object (e.g. list or dictionary)
and that other object is then modified or destroyed. Do not call any other
functions if this function returns false (0).

Called when no tabId is specified to an extension API call that accepts a
tabId parameter (e.g. chrome.tabs.*). |extension| and |browser| are the
source of the API call. Return the browser that will be acted on by the API
call or return NULL to act on |browser|. The returned browser must share
the same cef_request_context_t as |browser|. Incognito browsers should not
be considered unless the source extension has incognito access enabled, in
which case |include_incognito| will be true (1).

:can-access-browser (fn [CefExtensionHandler,CefExtension,CefBrowser,int,CefBrowser]) -> int
Called when the tabId associated with |target_browser| is specified to an
extension API call that accepts a tabId parameter (e.g. chrome.tabs.*).
|extension| and |browser| are the source of the API call. Return true (1)
to allow access of false (0) to deny access. Access to incognito browsers
should not be allowed unless the source extension has incognito access
enabled, in which case |include_incognito| will be true (1).

:get-extension-resource (fn [CefExtensionHandler,CefExtension,CefBrowser,CefStringUtf16,CefGetExtensionResourceCallback]) -> int
Called to retrieve an extension resource that would normally be loaded from
disk (e.g. if a file parameter is specified to chrome.tabs.executeScript).
|extension| and |browser| are the source of the resource request. |file| is
the requested relative file path. To handle the resource request return
true (1) and execute |callback| either synchronously or asynchronously. For
the default behavior which reads the resource from the extension directory
on disk return false (0). Localization substitutions will not be applied to
resources handled via this function.

Merge properties of a CefFileDialogCallback
Callback structure for asynchronous continuation of file dialog requests.

:cont (fn [CefFileDialogCallback,int,Pointer]) -> void
Continue the file selection. |selected_accept_filter| should be the 0-based
index of the value selected from the accept filters array passed to
cef_dialog_handler_t::OnFileDialog. |file_paths| should be a single value
or a list of values depending on the dialog mode. An NULL |file_paths|
value is treated the same as calling cancel().

:cancel (fn [CefFileDialogCallback]) -> void
Cancel the file selection.

Merge properties of a CefFindHandler
Implement this structure to handle events related to find results. The
functions of this structure will be called on the UI thread.

:on-find-result (fn [CefFindHandler,CefBrowser,int,int,CefRect,int,int]) -> void
Called to report find results returned by cef_browser_host_t::find().
|identifer| is the identifier passed to find(), |count| is the number of
matches currently identified, |selectionRect| is the location of where the
match was found (in window coordinates), |activeMatchOrdinal| is the
current position in the search results, and |finalUpdate| is true (1) if
this is the last find notification.

Merge properties of a CefFocusHandler
Implement this structure to handle events related to focus. The functions of
this structure will be called on the UI thread.

:on-take-focus (fn [CefFocusHandler,CefBrowser,int]) -> void
Called when the browser component is about to loose focus. For instance, if
focus was on the last HTML element and the user pressed the TAB key. |next|
will be true (1) if the browser is giving focus to the next component and
false (0) if the browser is giving focus to the previous component.

:on-set-focus (fn [CefFocusHandler,CefBrowser,int]) -> int
Called when the browser component is requesting focus. |source| indicates
where the focus request is originating from. Return false (0) to allow the
focus to be set or true (1) to cancel setting the focus.

:on-got-focus (fn [CefFocusHandler,CefBrowser]) -> void
Called when the browser component has received focus.

Merge properties of a CefFrame
Structure used to represent a frame in the browser window. When used in the
browser process the functions of this structure may be called on any thread
unless otherwise indicated in the comments. When used in the render process
the functions of this structure may only be called on the main thread.

:is-valid (fn [CefFrame]) -> int
True if this object is currently attached to a valid frame.

:undo (fn [CefFrame]) -> void
Execute undo in this frame.

:redo (fn [CefFrame]) -> void
Execute redo in this frame.

Execute copy in this frame.

:paste (fn [CefFrame]) -> void
Execute paste in this frame.

:del (fn [CefFrame]) -> void
Execute delete in this frame.

:select-all (fn [CefFrame]) -> void
Execute select all in this frame.

:view-source (fn [CefFrame]) -> void
Save this frame's HTML source to a temporary file and open it in the
default text viewing application. This function can only be called from the
browser process.

:get-source (fn [CefFrame,CefStringVisitor]) -> void
Retrieve this frame's HTML source as a string sent to the specified
visitor.

:get-text (fn [CefFrame,CefStringVisitor]) -> void
Retrieve this frame's display text as a string sent to the specified
visitor.

:load-request (fn [CefFrame,CefRequest]) -> void
Load the request represented by the |request| object.
WARNING: This function will fail with "bad IPC message" reason
INVALID_INITIATOR_ORIGIN (213) unless you first navigate to the request
origin using some other mechanism (LoadURL, link click, etc).

:load-url (fn [CefFrame,CefStringUtf16]) -> void
Load the specified |url|.

:execute-java-script (fn [CefFrame,CefStringUtf16,CefStringUtf16,int]) -> void
Execute a string of JavaScript code in this frame. The |script_url|
parameter is the URL where the script in question can be found, if any. The
renderer may request this URL to show the developer the source of the
error.  The |start_line| parameter is the base line number to use for error
reporting.

:is-main (fn [CefFrame]) -> int
Returns true (1) if this is the main (top-level) frame.

:is-focused (fn [CefFrame]) -> int
Returns true (1) if this is the focused frame.

:get-name (fn [CefFrame]) -> CefStringUtf16
Returns the name for this frame. If the frame has an assigned name (for
example, set via the iframe "name" attribute) then that value will be
returned. Otherwise a unique name will be constructed based on the frame
parent hierarchy. The main (top-level) frame will always have an NULL name
value.
The resulting string must be freed by calling cef_string_userfree_free().

:get-identifier (fn [CefFrame]) -> long
Returns the globally unique identifier for this frame or < 0 if the
underlying frame does not yet exist.

:get-parent (fn [CefFrame]) -> CefFrame
Returns the parent of this frame or NULL if this is the main (top-level)
frame.

:get-url (fn [CefFrame]) -> CefStringUtf16
Returns the URL currently loaded in this frame.
The resulting string must be freed by calling cef_string_userfree_free().

:get-browser (fn [CefFrame]) -> CefBrowser
Returns the browser that this frame belongs to.

:get-v8context (fn [CefFrame]) -> CefV8context
Get the V8 context associated with the frame. This function can only be
called from the render process.

:visit-dom (fn [CefFrame,CefDomvisitor]) -> void
Visit the DOM document. This function can only be called from the render
process.

:create-urlrequest (fn [CefFrame,CefRequest,CefUrlrequestClient]) -> CefUrlrequest
Create a new URL request that will be treated as originating from this
frame and the associated browser. This request may be intercepted by the
client via cef_resource_request_handler_t or cef_scheme_handler_factory_t.
Use cef_urlrequest_t::Create instead if you do not want the request to have
this association, in which case it may be handled differently (see
documentation on that function). Requests may originate from both the
browser process and the render process.
For requests originating from the browser process:
- POST data may only contain a single element of type PDE_TYPE_FILE or
PDE_TYPE_BYTES.
For requests originating from the render process:
- POST data may only contain a single element of type PDE_TYPE_BYTES.
- If the response contains Content-Disposition or Mime-Type header values
that would not normally be rendered then the response may receive
special handling inside the browser (for example, via the file download
code path instead of the URL request code path).
The |request| object will be marked as read-only after calling this
function.

:send-process-message (fn [CefFrame,int,CefProcessMessage]) -> void
Send a message to the specified |target_process|. Message delivery is not
guaranteed in all cases (for example, if the browser is closing,
navigating, or if the target process crashes). Send an ACK message back
from the target process if confirmation is required.

Merge properties of a CefGetExtensionResourceCallback
Callback structure used for asynchronous continuation of
cef_extension_handler_t::GetExtensionResource.

:cont (fn [CefGetExtensionResourceCallback,CefStreamReader]) -> void
Continue the request. Read the resource contents from |stream|.

:cancel (fn [CefGetExtensionResourceCallback]) -> void
Cancel the request.

Merge properties of a CefImage
Container for a single image represented at different scale factors. All
image representations should be the same size in density independent pixel
(DIP) units. For example, if the image at scale factor 1.0 is 100x100 pixels
then the image at scale factor 2.0 should be 200x200 pixels -- both images
will display with a DIP size of 100x100 units. The functions of this
structure can be called on any browser process thread.

:is-empty (fn [CefImage]) -> int
Returns true (1) if this Image is NULL.

:is-same (fn [CefImage,CefImage]) -> int
Returns true (1) if this Image and |that| Image share the same underlying
storage. Will also return true (1) if both images are NULL.

:add-bitmap (fn [CefImage,float,int,int,int,int,Pointer,SizeT]) -> int
Add a bitmap image representation for |scale_factor|. Only 32-bit RGBA/BGRA
formats are supported. |pixel_width| and |pixel_height| are the bitmap
representation size in pixel coordinates. |pixel_data| is the array of
pixel data and should be |pixel_width| x |pixel_height| x 4 bytes in size.
|color_type| and |alpha_type| values specify the pixel format.

:add-png (fn [CefImage,float,Pointer,SizeT]) -> int
Add a PNG image representation for |scale_factor|. |png_data| is the image
data of size |png_data_size|. Any alpha transparency in the PNG data will
be maintained.

:add-jpeg (fn [CefImage,float,Pointer,SizeT]) -> int
Create a JPEG image representation for |scale_factor|. |jpeg_data| is the
image data of size |jpeg_data_size|. The JPEG format does not support
transparency so the alpha byte will be set to 0xFF for all pixels.

:get-width (fn [CefImage]) -> SizeT
Returns the image width in density independent pixel (DIP) units.

:get-height (fn [CefImage]) -> SizeT
Returns the image height in density independent pixel (DIP) units.

:has-representation (fn [CefImage,float]) -> int
Returns true (1) if this image contains a representation for
|scale_factor|.

:remove-representation (fn [CefImage,float]) -> int
Removes the representation for |scale_factor|. Returns true (1) on success.

:get-representation-info (fn [CefImage,float,Pointer,Pointer,Pointer]) -> int
Returns information for the representation that most closely matches
|scale_factor|. |actual_scale_factor| is the actual scale factor for the
representation. |pixel_width| and |pixel_height| are the representation
size in pixel coordinates. Returns true (1) on success.

:get-as-bitmap (fn [CefImage,float,int,int,Pointer,Pointer]) -> CefBinaryValue
Returns the bitmap representation that most closely matches |scale_factor|.
Only 32-bit RGBA/BGRA formats are supported. |color_type| and |alpha_type|
values specify the desired output pixel format. |pixel_width| and
|pixel_height| are the output representation size in pixel coordinates.
Returns a cef_binary_value_t containing the pixel data on success or NULL
on failure.

:get-as-png (fn [CefImage,float,int,Pointer,Pointer]) -> CefBinaryValue
Returns the PNG representation that most closely matches |scale_factor|. If
|with_transparency| is true (1) any alpha transparency in the image will be
represented in the resulting PNG data. |pixel_width| and |pixel_height| are
the output representation size in pixel coordinates. Returns a
cef_binary_value_t containing the PNG image data on success or NULL on
failure.

:get-as-jpeg (fn [CefImage,float,int,Pointer,Pointer]) -> CefBinaryValue
Returns the JPEG representation that most closely matches |scale_factor|.
|quality| determines the compression level with 0 == lowest and 100 ==
highest. The JPEG format does not support alpha transparency and the alpha
channel, if any, will be discarded. |pixel_width| and |pixel_height| are
the output representation size in pixel coordinates. Returns a
cef_binary_value_t containing the JPEG image data on success or NULL on
failure.

Merge properties of a CefInsets
Structure representing insets.

Merge properties of a CefJsdialogCallback
Callback structure used for asynchronous continuation of JavaScript dialog
requests.

:cont (fn [CefJsdialogCallback,int,CefStringUtf16]) -> void
Continue the JS dialog request. Set |success| to true (1) if the OK button
was pressed. The |user_input| value should be specified for prompt dialogs.

Merge properties of a CefJsdialogHandler
Implement this structure to handle events related to JavaScript dialogs. The
functions of this structure will be called on the UI thread.

:on-jsdialog (fn [CefJsdialogHandler,CefBrowser,CefStringUtf16,int,CefStringUtf16,CefStringUtf16,CefJsdialogCallback,Pointer]) -> int
Called to run a JavaScript dialog. If |origin_url| is non-NULL it can be
passed to the CefFormatUrlForSecurityDisplay function to retrieve a secure
and user-friendly display string. The |default_prompt_text| value will be
specified for prompt dialogs only. Set |suppress_message| to true (1) and
return false (0) to suppress the message (suppressing messages is
preferable to immediately executing the callback as this is used to detect
presumably malicious behavior like spamming alert messages in
onbeforeunload). Set |suppress_message| to false (0) and return false (0)
to use the default implementation (the default implementation will show one
modal dialog at a time and suppress any additional dialog requests until
the displayed dialog is dismissed). Return true (1) if the application will
use a custom dialog or if the callback has been executed immediately.
Custom dialogs may be either modal or modeless. If a custom dialog is used
the application must execute |callback| once the custom dialog is
dismissed.

:on-before-unload-dialog (fn [CefJsdialogHandler,CefBrowser,CefStringUtf16,int,CefJsdialogCallback]) -> int
Called to run a dialog asking the user if they want to leave a page. Return
false (0) to use the default dialog implementation. Return true (1) if the
application will use a custom dialog or if the callback has been executed
immediately. Custom dialogs may be either modal or modeless. If a custom
dialog is used the application must execute |callback| once the custom
dialog is dismissed.

:on-reset-dialog-state (fn [CefJsdialogHandler,CefBrowser]) -> void
Called to cancel any pending dialogs and reset any saved dialog state. Will
be called due to events like page navigation irregardless of whether any
dialogs are currently pending.

:on-dialog-closed (fn [CefJsdialogHandler,CefBrowser]) -> void
Called when the default implementation dialog is closed.

Merge properties of a CefKeyEvent
Structure representing keyboard event information.

:type cef_key_event_type_t
The type of keyboard event.

:modifiers uint32
Bit flags describing any pressed modifier keys. See
cef_event_flags_t for values.

:windows-key-code int
The Windows key code for the key event. This value is used by the DOM
specification. Sometimes it comes directly from the event (i.e. on
Windows) and sometimes it's determined using a mapping function. See
WebCore/platform/chromium/KeyboardCodes.h for the list of values.

:native-key-code int
The actual key code genenerated by the platform.

:is-system-key int
Indicates whether the event is considered a "system key" event (see
http://msdn.microsoft.com/en-us/library/ms646286(VS.85).aspx for details).
This value will always be false on non-Windows platforms.

:character char16
The character generated by the keystroke.

:unmodified-character char16
Same as |character| but unmodified by any concurrently-held modifiers
(except shift). This is useful for working out shortcut keys.

:focus-on-editable-field int
True if the focus is currently on an editable field on the page. This is
useful for determining if standard key events should be intercepted.

Merge properties of a CefKeyboardHandler
Implement this structure to handle events related to keyboard input. The
functions of this structure will be called on the UI thread.

:on-pre-key-event (fn [CefKeyboardHandler,CefBrowser,CefKeyEvent,Pointer,Pointer]) -> int
Called before a keyboard event is sent to the renderer. |event| contains
information about the keyboard event. |os_event| is the operating system
event message, if any. Return true (1) if the event was handled or false
(0) otherwise. If the event will be handled in on_key_event() as a keyboard
shortcut set |is_keyboard_shortcut| to true (1) and return false (0).

:on-key-event (fn [CefKeyboardHandler,CefBrowser,CefKeyEvent,Pointer]) -> int
Called after the renderer and JavaScript in the page has had a chance to
handle the event. |event| contains information about the keyboard event.
|os_event| is the operating system event message, if any. Return true (1)
if the keyboard event was handled or false (0) otherwise.

Merge properties of a CefLifeSpanHandler
Implement this structure to handle events related to browser life span. The
functions of this structure will be called on the UI thread unless otherwise
indicated.

:on-before-popup (fn [CefLifeSpanHandler,CefBrowser,CefFrame,CefStringUtf16,CefStringUtf16,int,int,CefPopupFeatures,Pointer,Pointer,CefBrowserSettings,Pointer,Pointer]) -> int
Called on the UI thread before a new popup browser is created. The
|browser| and |frame| values represent the source of the popup request. The
|target_url| and |target_frame_name| values indicate where the popup
browser should navigate and may be NULL if not specified with the request.
The |target_disposition| value indicates where the user intended to open
the popup (e.g. current tab, new tab, etc). The |user_gesture| value will
be true (1) if the popup was opened via explicit user gesture (e.g.
clicking a link) or false (0) if the popup opened automatically (e.g. via
the DomContentLoaded event). The |popupFeatures| structure contains
additional information about the requested popup window. To allow creation
of the popup browser optionally modify |windowInfo|, |client|, |settings|
and |no_javascript_access| and return false (0). To cancel creation of the
popup browser return true (1). The |client| and |settings| values will
default to the source browser's values. If the |no_javascript_access| value
is set to false (0) the new browser will not be scriptable and may not be
hosted in the same renderer process as the source browser. Any
modifications to |windowInfo| will be ignored if the parent browser is
wrapped in a cef_browser_view_t. Popup browser creation will be canceled if
the parent browser is destroyed before the popup browser creation completes
(indicated by a call to OnAfterCreated for the popup browser). The
|extra_info| parameter provides an opportunity to specify extra information
specific to the created popup browser that will be passed to
cef_render_process_handler_t::on_browser_created() in the render process.

:on-after-created (fn [CefLifeSpanHandler,CefBrowser]) -> void
Called after a new browser is created. This callback will be the first
notification that references |browser|.

:do-close (fn [CefLifeSpanHandler,CefBrowser]) -> int
Called when a browser has recieved a request to close. This may result
directly from a call to cef_browser_host_t::*close_browser() or indirectly
if the browser is parented to a top-level window created by CEF and the
user attempts to close that window (by clicking the 'X', for example). The
do_close() function will be called after the JavaScript 'onunload' event
has been fired.
An application should handle top-level owner window close notifications by
calling cef_browser_host_t::try_close_browser() or
cef_browser_host_t::CloseBrowser(false (0)) instead of allowing the window
to close immediately (see the examples below). This gives CEF an
opportunity to process the 'onbeforeunload' event and optionally cancel the
close before do_close() is called.
When windowed rendering is enabled CEF will internally create a window or
view to host the browser. In that case returning false (0) from do_close()
will send the standard close notification to the browser's top-level owner
window (e.g. WM_CLOSE on Windows, performClose: on OS X, "delete_event" on
Linux or cef_window_delegate_t::can_close() callback from Views). If the
browser's host window/view has already been destroyed (via view hierarchy
tear-down, for example) then do_close() will not be called for that browser
since is no longer possible to cancel the close.
When windowed rendering is disabled returning false (0) from do_close()
will cause the browser object to be destroyed immediately.
If the browser's top-level owner window requires a non-standard close
notification then send that notification from do_close() and return true
(1).
The cef_life_span_handler_t::on_before_close() function will be called
after do_close() (if do_close() is called) and immediately before the
browser object is destroyed. The application should only exit after
on_before_close() has been called for all existing browsers.
The below examples describe what should happen during window close when the
browser is parented to an application-provided top-level window.
Example 1: Using cef_browser_host_t::try_close_browser(). This is
recommended for clients using standard close handling and windows created
on the browser process UI thread. 1.  User clicks the window close button
which sends a close notification to
the application's top-level window.
2.  Application's top-level window receives the close notification and
calls TryCloseBrowser() (which internally calls CloseBrowser(false)).
TryCloseBrowser() returns false so the client cancels the window close.
3.  JavaScript 'onbeforeunload' handler executes and shows the close
confirmation dialog (which can be overridden via
CefJSDialogHandler::OnBeforeUnloadDialog()).
4.  User approves the close. 5.  JavaScript 'onunload' handler executes. 6.
CEF sends a close notification to the application's top-level window
(because DoClose() returned false by default).
7.  Application's top-level window receives the close notification and
calls TryCloseBrowser(). TryCloseBrowser() returns true so the client
allows the window close.
8.  Application's top-level window is destroyed. 9.  Application's
on_before_close() handler is called and the browser object
is destroyed.
10. Application exits by calling cef_quit_message_loop() if no other
browsers
exist.
Example 2: Using cef_browser_host_t::CloseBrowser(false (0)) and
implementing the do_close() callback. This is recommended for clients using
non-standard close handling or windows that were not created on the browser
process UI thread. 1.  User clicks the window close button which sends a
close notification to
the application's top-level window.
2.  Application's top-level window receives the close notification and:
A. Calls CefBrowserHost::CloseBrowser(false).
B. Cancels the window close.
3.  JavaScript 'onbeforeunload' handler executes and shows the close
confirmation dialog (which can be overridden via
CefJSDialogHandler::OnBeforeUnloadDialog()).
4.  User approves the close. 5.  JavaScript 'onunload' handler executes. 6.
Application's do_close() handler is called. Application will:
A. Set a flag to indicate that the next close attempt will be allowed.
B. Return false.
7.  CEF sends an close notification to the application's top-level window.
8.  Application's top-level window receives the close notification and
allows the window to close based on the flag from #6B.
9.  Application's top-level window is destroyed. 10. Application's
on_before_close() handler is called and the browser object
is destroyed.
11. Application exits by calling cef_quit_message_loop() if no other
browsers
exist.

:on-before-close (fn [CefLifeSpanHandler,CefBrowser]) -> void
Called just before a browser is destroyed. Release all references to the
browser object and do not attempt to execute any functions on the browser
object (other than GetIdentifier or IsSame) after this callback returns.
This callback will be the last notification that references |browser| on
the UI thread. Any in-progress network requests associated with |browser|
will be aborted when the browser is destroyed, and
cef_resource_request_handler_t callbacks related to those requests may
still arrive on the IO thread after this function is called. See do_close()
documentation for additional usage information.

Merge properties of a CefListValue
Structure representing a list value. Can be used on any process and thread.

:is-valid (fn [CefListValue]) -> int
Returns true (1) if this object is valid. This object may become invalid if

change. Otherwise, ownership will be transferred to this object and the
|value| reference will be invalidated.

:set-dictionary (fn [CefListValue,SizeT,CefDictionaryValue]) -> int
Sets the value at the specified index as type dict. Returns true (1) if the
value was set successfully. If |value| is currently owned by another object
then the value will be copied and the |value| reference will not change.

or render process main thread (TID_RENDERER).

:on-loading-state-change (fn [CefLoadHandler,CefBrowser,int,int,int]) -> void
Called when the loading state has changed. This callback will be executed
twice -- once when loading is initiated either programmatically or by user
action, and once when loading is terminated due to completion, cancellation
of failure. It will be called before any calls to OnLoadStart and after all
calls to OnLoadError and/or OnLoadEnd.

:on-load-start (fn [CefLoadHandler,CefBrowser,CefFrame,int]) -> void
Called after a navigation has been committed and before the browser begins
loading contents in the frame. The |frame| value will never be NULL -- call
the is_main() function to check if this frame is the main frame.
|transition_type| provides information about the source of the navigation
and an accurate value is only available in the browser process. Multiple
frames may be loading at the same time. Sub-frames may start or continue
loading after the main frame load has ended. This function will not be
called for same page navigations (fragments, history state, etc.) or for
navigations that fail or are canceled before commit. For notification of
overall browser load status use OnLoadingStateChange instead.

:on-load-end (fn [CefLoadHandler,CefBrowser,CefFrame,int]) -> void
Called when the browser is done loading a frame. The |frame| value will
never be NULL -- call the is_main() function to check if this frame is the
main frame. Multiple frames may be loading at the same time. Sub-frames may
start or continue loading after the main frame load has ended. This
function will not be called for same page navigations (fragments, history
state, etc.) or for navigations that fail or are canceled before commit.
For notification of overall browser load status use OnLoadingStateChange
instead.

:on-load-error (fn [CefLoadHandler,CefBrowser,CefFrame,int,CefStringUtf16,CefStringUtf16]) -> void
Called when a navigation fails or is canceled. This function may be called
by itself if before commit or in combination with OnLoadStart/OnLoadEnd if
after commit. |errorCode| is the error code number, |errorText| is the
error text and |failedUrl| is the URL that failed to load. See
net\base\net_error_list.h for complete descriptions of the error codes.

the browser process to track a single request across multiple callbacks.

Merge properties of a CefRequestCallback
Callback structure used for asynchronous continuation of url requests.

:cont (fn [CefRequestCallback,int]) -> void
Continue the url request. If |allow| is true (1) the request will be
continued. Otherwise, the request will be canceled.

:cancel (fn [CefRequestCallback]) -> void
Cancel the url request.

Merge properties of a CefRequestContext
A request context provides request handling for a set of related browser or
URL request objects. A request context can be specified when creating a new
browser via the cef_browser_host_t static factory functions or when creating
a new URL request via the cef_urlrequest_t static factory functions. Browser
objects with different request contexts will never be hosted in the same
render process. Browser objects with the same request context may or may not
be hosted in the same render process depending on the process model. Browser
objects created indirectly via the JavaScript window.open function or
targeted links will share the same render process and the same request
context as the source browser. When running in single-process mode there is
only a single render process (the main process) and so all browsers created
in single-process mode will share the same request context. This will be the
first request context passed into a cef_browser_host_t static factory
function and all other request context objects will be ignored.

:is-same (fn [CefRequestContext,CefRequestContext]) -> int
Returns true (1) if this object is pointing to the same context as |that|
object.

:is-sharing-with (fn [CefRequestContext,CefRequestContext]) -> int
Returns true (1) if this object is sharing the same storage as |that|
object.

:is-global (fn [CefRequestContext]) -> int

context argument.

:get-handler (fn [CefRequestContext]) -> CefRequestContextHandler
Returns the handler for this context if any.

:get-cache-path (fn [CefRequestContext]) -> CefStringUtf16
Returns the cache path for this object. If NULL an "incognito mode" in-
memory cache is being used.
The resulting string must be freed by calling cef_string_userfree_free().

:get-cookie-manager (fn [CefRequestContext,CefCompletionCallback]) -> CefCookieManager
Returns the cookie manager for this object. If |callback| is non-NULL it
will be executed asnychronously on the IO thread after the manager's
storage has been initialized.

:register-scheme-handler-factory (fn [CefRequestContext,CefStringUtf16,CefStringUtf16,CefSchemeHandlerFactory]) -> int
Register a scheme handler factory for the specified |scheme_name| and
optional |domain_name|. An NULL |domain_name| value for a standard scheme
will cause the factory to match all domain names. The |domain_name| value
will be ignored for non-standard schemes. If |scheme_name| is a built-in
scheme and no handler is returned by |factory| then the built-in scheme
handler factory will be called. If |scheme_name| is a custom scheme then
you must also implement the cef_app_t::on_register_custom_schemes()
function in all processes. This function may be called multiple times to
change or remove the factory that matches the specified |scheme_name| and
optional |domain_name|. Returns false (0) if an error occurs. This function
may be called on any thread in the browser process.

:clear-scheme-handler-factories (fn [CefRequestContext]) -> int
Clear all registered scheme handler factories. Returns false (0) on error.
This function may be called on any thread in the browser process.

:purge-plugin-list-cache (fn [CefRequestContext,int]) -> void
Tells all renderer processes associated with this context to throw away
their plugin list cache. If |reload_pages| is true (1) they will also
reload all pages with plugins.
cef_request_context_handler_t::OnBeforePluginLoad may be called to rebuild
the plugin list cache.

:has-preference (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if a preference with the specified |name| exists. This
function must be called on the browser process UI thread.

:get-preference (fn [CefRequestContext,CefStringUtf16]) -> CefValue
Returns the value for the preference with the specified |name|. Returns
NULL if the preference does not exist. The returned object contains a copy
of the underlying preference value and modifications to the returned object
will not modify the underlying preference value. This function must be
called on the browser process UI thread.

:get-all-preferences (fn [CefRequestContext,int]) -> CefDictionaryValue
Returns all preferences as a dictionary. If |include_defaults| is true (1)
then preferences currently at their default value will be included. The
returned object contains a copy of the underlying preference values and
modifications to the returned object will not modify the underlying
preference values. This function must be called on the browser process UI
thread.

:can-set-preference (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if the preference with the specified |name| can be
modified using SetPreference. As one example preferences set via the
command-line usually cannot be modified. This function must be called on
the browser process UI thread.

:set-preference (fn [CefRequestContext,CefStringUtf16,CefValue,CefStringUtf16]) -> int
Set the |value| associated with preference |name|. Returns true (1) if the
value is set successfully and false (0) otherwise. If |value| is NULL the
preference will be restored to its default value. If setting the preference
fails then |error| will be populated with a detailed description of the
problem. This function must be called on the browser process UI thread.

:clear-certificate-exceptions (fn [CefRequestContext,CefCompletionCallback]) -> void
Clears all certificate exceptions that were added as part of handling
cef_request_handler_t::on_certificate_error(). If you call this it is
recommended that you also call close_all_connections() or you risk not
being prompted again for server certificates if you reconnect quickly. If
|callback| is non-NULL it will be executed on the UI thread after
completion.

:clear-http-auth-credentials (fn [CefRequestContext,CefCompletionCallback]) -> void
Clears all HTTP authentication credentials that were added as part of
handling GetAuthCredentials. If |callback| is non-NULL it will be executed
on the UI thread after completion.

:close-all-connections (fn [CefRequestContext,CefCompletionCallback]) -> void
Clears all active and idle connections that Chromium currently has. This is
only recommended if you have released all other CEF objects but don't yet
want to call cef_shutdown(). If |callback| is non-NULL it will be executed
on the UI thread after completion.

:resolve-host (fn [CefRequestContext,CefStringUtf16,CefResolveCallback]) -> void
Attempts to resolve |origin| to a list of associated IP addresses.
|callback| will be executed on the UI thread after completion.

:load-extension (fn [CefRequestContext,CefStringUtf16,CefDictionaryValue,CefExtensionHandler]) -> void
Load an extension.
If extension resources will be read from disk using the default load
implementation then |root_directory| should be the absolute path to the
extension resources directory and |manifest| should be NULL. If extension
resources will be provided by the client (e.g. via cef_request_handler_t
and/or cef_extension_handler_t) then |root_directory| should be a path
component unique to the extension (if not absolute this will be internally
prefixed with the PK_DIR_RESOURCES path) and |manifest| should contain the
contents that would otherwise be read from the "manifest.json" file on
disk.
The loaded extension will be accessible in all contexts sharing the same
storage (HasExtension returns true (1)). However, only the context on which
this function was called is considered the loader (DidLoadExtension returns
true (1)) and only the loader will receive cef_request_context_handler_t
callbacks for the extension.
cef_extension_handler_t::OnExtensionLoaded will be called on load success
or cef_extension_handler_t::OnExtensionLoadFailed will be called on load
failure.
If the extension specifies a background script via the "background"
manifest key then cef_extension_handler_t::OnBeforeBackgroundBrowser will
be called to create the background browser. See that function for
additional information about background scripts.
For visible extension views the client application should evaluate the
manifest to determine the correct extension URL to load and then pass that
URL to the cef_browser_host_t::CreateBrowser* function after the extension
has loaded. For example, the client can look for the "browser_action"
manifest key as documented at
https://developer.chrome.com/extensions/browserAction. Extension URLs take
the form "chrome-extension://<extension_id>/<path>".
Browsers that host extensions differ from normal browsers as follows:
- Can access chrome.* JavaScript APIs if allowed by the manifest. Visit
chrome://extensions-support for the list of extension APIs currently
supported by CEF.
- Main frame navigation to non-extension content is blocked.
- Pinch-zooming is disabled.
- CefBrowserHost::GetExtension returns the hosted extension.
- CefBrowserHost::IsBackgroundHost returns true for background hosts.
See https://developer.chrome.com/extensions for extension implementation
and usage documentation.

:did-load-extension (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if this context was used to load the extension identified
by |extension_id|. Other contexts sharing the same storage will also have
access to the extension (see HasExtension). This function must be called on
the browser process UI thread.

:has-extension (fn [CefRequestContext,CefStringUtf16]) -> int
Returns true (1) if this context has access to the extension identified by
|extension_id|. This may not be the context that was used to load the
extension (see DidLoadExtension). This function must be called on the
browser process UI thread.

:get-extensions (fn [CefRequestContext,Pointer]) -> int
Retrieve the list of all extensions that this context has access to (see
HasExtension). |extension_ids| will be populated with the list of extension
ID values. Returns true (1) on success. This function must be called on the
browser process UI thread.

:get-extension (fn [CefRequestContext,CefStringUtf16]) -> CefExtension
Returns the extension matching |extension_id| or NULL if no matching
extension is accessible in this context (see HasExtension). This function
must be called on the browser process UI thread.

:get-media-router (fn [CefRequestContext]) -> CefMediaRouter
Returns the MediaRouter object associated with this context.

Merge properties of a CefRequestContextHandler
Implement this structure to provide handler implementations. The handler
instance will not be released until all objects related to the context have
been destroyed.

:on-request-context-initialized (fn [CefRequestContextHandler,CefRequestContext]) -> void
Called on the browser process UI thread immediately after the request
context has been initialized.

:on-before-plugin-load (fn [CefRequestContextHandler,CefStringUtf16,CefStringUtf16,int,CefStringUtf16,CefWebPluginInfo,int]) -> int
Called on multiple browser process threads before a plugin instance is
loaded. |mime_type| is the mime type of the plugin that will be loaded.
|plugin_url| is the content URL that the plugin will load and may be NULL.
|is_main_frame| will be true (1) if the plugin is being loaded in the main
(top-level) frame, |top_origin_url| is the URL for the top-level frame that
contains the plugin when loading a specific plugin instance or NULL when
building the initial list of enabled plugins for 'navigator.plugins'
JavaScript state. |plugin_info| includes additional information about the
plugin that will be loaded. |plugin_policy| is the recommended policy.
Modify |plugin_policy| and return true (1) to change the policy. Return
false (0) to use the recommended policy. The default plugin policy can be
set at runtime using the `--plugin-policy=[allow|detect|block]` command-
line flag. Decisions to mark a plugin as disabled by setting
|plugin_policy| to PLUGIN_POLICY_DISABLED may be cached when
|top_origin_url| is NULL. To purge the plugin list cache and potentially
trigger new calls to this function call
cef_request_context_t::PurgePluginListCache.

:get-resource-request-handler (fn [CefRequestContextHandler,CefBrowser,CefFrame,CefRequest,int,int,CefStringUtf16,Pointer]) -> CefResourceRequestHandler
Called on the browser process IO thread before a resource request is
initiated. The |browser| and |frame| values represent the source of the
request, and may be NULL for requests originating from service workers or
cef_urlrequest_t. |request| represents the request contents and cannot be
modified in this callback. |is_navigation| will be true (1) if the resource
request is a navigation. |is_download| will be true (1) if the resource
request is a download. |request_initiator| is the origin (scheme + domain)
of the page that initiated the request. Set |disable_default_handling| to
true (1) to disable default handling of the request, in which case it will
need to be handled via cef_resource_request_handler_t::GetResourceHandler
or it will be canceled. To allow the resource load to proceed with default
handling return NULL. To specify a handler for the resource return a
cef_resource_request_handler_t object. This function will not be called if
the client associated with |browser| returns a non-NULL value from
cef_request_handler_t::GetResourceRequestHandler for the same request
(identified by cef_request_t::GetIdentifier).

Merge properties of a CefRequestContextSettings
Request context initialization settings. Specify NULL or 0 to get the
recommended default values.

:size size_t
Size of this structure.

:cache-path cef_string_t
The location where cache data for this request context will be stored on
disk. If this value is non-empty then it must be an absolute path that is
either equal to or a child directory of CefSettings.root_cache_path. If
this value is empty then browsers will be created in "incognito mode" where
in-memory caches are used for storage and no data is persisted to disk.
HTML5 databases such as localStorage will only persist across sessions if a
cache path is specified. To share the global browser cache and related
configuration set this value to match the CefSettings.cache_path value.

:persist-session-cookies int
To persist session cookies (cookies without an expiry date or validity
interval) by default when using the global cookie manager set this value to
true (1). Session cookies are generally intended to be transient and most
Web browsers do not persist them. Can be set globally using the
CefSettings.persist_session_cookies value. This value will be ignored if
|cache_path| is empty or if it matches the CefSettings.cache_path value.

:persist-user-preferences int
To persist user preferences as a JSON file in the cache path directory set
this value to true (1). Can be set globally using the
CefSettings.persist_user_preferences value. This value will be ignored if
|cache_path| is empty or if it matches the CefSettings.cache_path value.

:ignore-certificate-errors int
Set to true (1) to ignore errors related to invalid SSL certificates.
Enabling this setting can lead to potential security vulnerabilities like
"man in the middle" attacks. Applications that load content from the
internet should not enable this setting. Can be set globally using the
CefSettings.ignore_certificate_errors value. This value will be ignored if
|cache_path| matches the CefSettings.cache_path value.

:accept-language-list cef_string_t
Comma delimited ordered list of language codes without any whitespace that
will be used in the "Accept-Language" HTTP header. Can be set globally
using the CefSettings.accept_language_list value or overridden on a per-
browser basis using the CefBrowserSettings.accept_language_list value. If
all values are empty then "en-US,en" will be used. This value will be
ignored if |cache_path| matches the CefSettings.cache_path value.

Merge properties of a CefRequestHandler
Implement this structure to handle events related to browser requests. The
functions of this structure will be called on the thread indicated.

:on-before-browse (fn [CefRequestHandler,CefBrowser,CefFrame,CefRequest,int,int]) -> int
Called on the UI thread before browser navigation. Return true (1) to
cancel the navigation or false (0) to allow the navigation to proceed. The
|request| object cannot be modified in this callback.
cef_load_handler_t::OnLoadingStateChange will be called twice in all cases.
If the navigation is allowed cef_load_handler_t::OnLoadStart and
cef_load_handler_t::OnLoadEnd will be called. If the navigation is canceled
cef_load_handler_t::OnLoadError will be called with an |errorCode| value of
ERR_ABORTED. The |user_gesture| value will be true (1) if the browser
navigated via explicit user gesture (e.g. clicking a link) or false (0) if
it navigated automatically (e.g. via the DomContentLoaded event).

:on-open-urlfrom-tab (fn [CefRequestHandler,CefBrowser,CefFrame,CefStringUtf16,int,int]) -> int
Called on the UI thread before OnBeforeBrowse in certain limited cases
where navigating a new or different browser might be desirable. This
includes user-initiated navigation that might open in a special way (e.g.
links clicked via middle-click or ctrl + left-click) and certain types of
cross-origin navigation initiated from the renderer process (e.g.
navigating the top-level frame to/from a file URL). The |browser| and
|frame| values represent the source of the navigation. The
|target_disposition| value indicates where the user intended to navigate
the browser based on standard Chromium behaviors (e.g. current tab, new
tab, etc). The |user_gesture| value will be true (1) if the browser
navigated via explicit user gesture (e.g. clicking a link) or false (0) if
it navigated automatically (e.g. via the DomContentLoaded event). Return
true (1) to cancel the navigation or false (0) to allow the navigation to
proceed in the source browser's top-level frame.

:get-resource-request-handler (fn [CefRequestHandler,CefBrowser,CefFrame,CefRequest,int,int,CefStringUtf16,Pointer]) -> CefResourceRequestHandler
Called on the browser process IO thread before a resource request is
initiated. The |browser| and |frame| values represent the source of the
request. |request| represents the request contents and cannot be modified
in this callback. |is_navigation| will be true (1) if the resource request
is a navigation. |is_download| will be true (1) if the resource request is
a download. |request_initiator| is the origin (scheme + domain) of the page
that initiated the request. Set |disable_default_handling| to true (1) to
disable default handling of the request, in which case it will need to be
handled via cef_resource_request_handler_t::GetResourceHandler or it will
be canceled. To allow the resource load to proceed with default handling
return NULL. To specify a handler for the resource return a
cef_resource_request_handler_t object. If this callback returns NULL the
same function will be called on the associated
cef_request_context_handler_t, if any.

:get-auth-credentials (fn [CefRequestHandler,CefBrowser,CefStringUtf16,int,CefStringUtf16,int,CefStringUtf16,CefStringUtf16,CefAuthCallback]) -> int
Called on the IO thread when the browser needs credentials from the user.
|origin_url| is the origin making this authentication request. |isProxy|
indicates whether the host is a proxy server. |host| contains the hostname
and |port| contains the port number. |realm| is the realm of the challenge
and may be NULL. |scheme| is the authentication scheme used, such as
"basic" or "digest", and will be NULL if the source of the request is an
FTP server. Return true (1) to continue the request and call
cef_auth_callback_t::cont() either in this function or at a later time when
the authentication information is available. Return false (0) to cancel the
request immediately.

:on-quota-request (fn [CefRequestHandler,CefBrowser,CefStringUtf16,long,CefRequestCallback]) -> int
Called on the IO thread when JavaScript requests a specific storage quota
size via the webkitStorageInfo.requestQuota function. |origin_url| is the
origin of the page making the request. |new_size| is the requested quota
size in bytes. Return true (1) to continue the request and call
cef_request_callback_t::cont() either in this function or at a later time
to grant or deny the request. Return false (0) to cancel the request
immediately.

:on-certificate-error (fn [CefRequestHandler,CefBrowser,int,CefStringUtf16,CefSslinfo,CefRequestCallback]) -> int
Called on the UI thread to handle requests for URLs with an invalid SSL
certificate. Return true (1) and call cef_request_callback_t::cont() either
in this function or at a later time to continue or cancel the request.
Return false (0) to cancel the request immediately. If
CefSettings.ignore_certificate_errors is set all invalid certificates will
be accepted without calling this function.

:on-select-client-certificate (fn [CefRequestHandler,CefBrowser,int,CefStringUtf16,int,SizeT,Pointer,CefSelectClientCertificateCallback]) -> int
Called on the UI thread when a client certificate is being requested for
authentication. Return false (0) to use the default behavior and
automatically select the first certificate available. Return true (1) and
call cef_select_client_certificate_callback_t::Select either in this
function or at a later time to select a certificate. Do not call Select or
call it with NULL to continue without using any certificate. |isProxy|
indicates whether the host is an HTTPS proxy or the origin server. |host|
and |port| contains the hostname and port of the SSL server. |certificates|
is the list of certificates to choose from; this list has already been
pruned by Chromium so that it only contains certificates from issuers that
the server trusts.

:on-plugin-crashed (fn [CefRequestHandler,CefBrowser,CefStringUtf16]) -> void
Called on the browser process UI thread when a plugin has crashed.
|plugin_path| is the path of the plugin that crashed.

:on-render-view-ready (fn [CefRequestHandler,CefBrowser]) -> void
Called on the browser process UI thread when the render view associated
with |browser| is ready to receive/handle IPC messages in the render
process.

:on-render-process-terminated (fn [CefRequestHandler,CefBrowser,int]) -> void
Called on the browser process UI thread when the render process terminates
unexpectedly. |status| indicates how the process terminated.

:on-document-available-in-main-frame (fn [CefRequestHandler,CefBrowser]) -> void

the main frame has been created.

Merge properties of a CefResolveCallback
Callback structure for cef_request_context_t::ResolveHost.

:on-resolve-completed (fn [CefResolveCallback,int,Pointer]) -> void
Called on the UI thread after the ResolveHost request has completed.
|result| will be the result code. |resolved_ips| will be the list of
resolved IP addresses or NULL if the resolution failed.

Merge properties of a CefResourceBundleHandler
Structure used to implement a custom resource bundle structure. See
CefSettings for additional options related to resource bundle loading. The
functions of this structure may be called on multiple threads.

:get-localized-string (fn [CefResourceBundleHandler,int,CefStringUtf16]) -> int
Called to retrieve a localized translation for the specified |string_id|.
To provide the translation set |string| to the translation string and
return true (1). To use the default translation return false (0). Include
cef_pack_strings.h for a listing of valid string ID values.

:get-data-resource (fn [CefResourceBundleHandler,int,Pointer,Pointer]) -> int
Called to retrieve data for the specified scale independent |resource_id|.
To provide the resource data set |data| and |data_size| to the data pointer
and size respectively and return true (1). To use the default resource data
return false (0). The resource data will not be copied and must remain
resident in memory. Include cef_pack_resources.h for a listing of valid
resource ID values.

:get-data-resource-for-scale (fn [CefResourceBundleHandler,int,int,Pointer,Pointer]) -> int
Called to retrieve data for the specified |resource_id| nearest the scale
factor |scale_factor|. To provide the resource data set |data| and
|data_size| to the data pointer and size respectively and return true (1).
To use the default resource data return false (0). The resource data will
not be copied and must remain resident in memory. Include
cef_pack_resources.h for a listing of valid resource ID values.

Merge properties of a CefResourceHandler
Structure used to implement a custom request handler structure. The functions
of this structure will be called on the IO thread unless otherwise indicated.

:open (fn [CefResourceHandler,CefRequest,Pointer,CefCallback]) -> int
Open the response stream. To handle the request immediately set
|handle_request| to true (1) and return true (1). To decide at a later time
set |handle_request| to false (0), return true (1), and execute |callback|
to continue or cancel the request. To cancel the request immediately set
|handle_request| to true (1) and return false (0). This function will be
called in sequence but not from a dedicated thread. For backwards
compatibility set |handle_request| to false (0) and return false (0) and
the ProcessRequest function will be called.

:process-request (fn [CefResourceHandler,CefRequest,CefCallback]) -> int
Begin processing the request. To handle the request return true (1) and
call cef_callback_t::cont() once the response header information is
available (cef_callback_t::cont() can also be called from inside this
function if header information is available immediately). To cancel the
request return false (0).
WARNING: This function is deprecated. Use Open instead.

:get-response-headers (fn [CefResourceHandler,CefResponse,Pointer,CefStringUtf16]) -> void
Retrieve response header information. If the response length is not known
set |response_length| to -1 and read_response() will be called until it
returns false (0). If the response length is known set |response_length| to
a positive value and read_response() will be called until it returns false
(0) or the specified number of bytes have been read. Use the |response|
object to set the mime type, http status code and other optional header
values. To redirect the request to a new URL set |redirectUrl| to the new
URL. |redirectUrl| can be either a relative or fully qualified URL. It is
also possible to set |response| to a redirect http status code and pass the
new URL via a Location header. Likewise with |redirectUrl| it is valid to
set a relative or fully qualified URL as the Location header value. If an
error occured while setting up the request you can call set_error() on
|response| to indicate the error condition.

:skip (fn [CefResourceHandler,long,Pointer,CefResourceSkipCallback]) -> int
Skip response data when requested by a Range header. Skip over and discard
|bytes_to_skip| bytes of response data. If data is available immediately
set |bytes_skipped| to the number of bytes skipped and return true (1). To
read the data at a later time set |bytes_skipped| to 0, return true (1) and
execute |callback| when the data is available. To indicate failure set
|bytes_skipped| to < 0 (e.g. -2 for ERR_FAILED) and return false (0). This
function will be called in sequence but not from a dedicated thread.

:read (fn [CefResourceHandler,Pointer,int,Pointer,CefResourceReadCallback]) -> int
Read response data. If data is available immediately copy up to
|bytes_to_read| bytes into |data_out|, set |bytes_read| to the number of
bytes copied, and return true (1). To read the data at a later time keep a
pointer to |data_out|, set |bytes_read| to 0, return true (1) and execute
|callback| when the data is available (|data_out| will remain valid until
the callback is executed). To indicate response completion set |bytes_read|
to 0 and return false (0). To indicate failure set |bytes_read| to < 0
(e.g. -2 for ERR_FAILED) and return false (0). This function will be called
in sequence but not from a dedicated thread. For backwards compatibility
set |bytes_read| to -1 and return false (0) and the ReadResponse function
will be called.

:read-response (fn [CefResourceHandler,Pointer,int,Pointer,CefCallback]) -> int
Read response data. If data is available immediately copy up to
|bytes_to_read| bytes into |data_out|, set |bytes_read| to the number of
bytes copied, and return true (1). To read the data at a later time set
|bytes_read| to 0, return true (1) and call cef_callback_t::cont() when the
data is available. To indicate response completion return false (0).
WARNING: This function is deprecated. Use Skip and Read instead.

:cancel (fn [CefResourceHandler]) -> void
Request processing has been canceled.

Merge properties of a CefResourceReadCallback
Callback for asynchronous continuation of cef_resource_handler_t::read().

:cont (fn [CefResourceReadCallback,int]) -> void
Callback for asynchronous continuation of read(). If |bytes_read| == 0 the
response will be considered complete. If |bytes_read| > 0 then read() will
be called again until the request is complete (based on either the result
or the expected content length). If |bytes_read| < 0 then the request will
fail and the |bytes_read| value will be treated as the error code.

Merge properties of a CefResourceRequestHandler
Implement this structure to handle events related to browser requests. The
functions of this structure will be called on the IO thread unless otherwise
indicated.

:get-cookie-access-filter (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest]) -> CefCookieAccessFilter
Called on the IO thread before a resource request is loaded. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. To
optionally filter cookies for the request return a

modified in this callback.

:on-before-resource-load (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefRequestCallback]) -> int
Called on the IO thread before a resource request is loaded. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. To redirect
or change the resource load optionally modify |request|. Modification of
the request URL will be treated as a redirect. Return RV_CONTINUE to
continue the request immediately. Return RV_CONTINUE_ASYNC and call
cef_request_callback_t:: cont() at a later time to continue or cancel the
request asynchronously. Return RV_CANCEL to cancel the request immediately.

:get-resource-handler (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest]) -> CefResourceHandler
Called on the IO thread before a resource is loaded. The |browser| and
|frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. To allow the
resource to load using the default network loader return NULL. To specify a
handler for the resource return a cef_resource_handler_t object. The
|request| object cannot not be modified in this callback.

:on-resource-redirect (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse,CefStringUtf16]) -> void
Called on the IO thread when a resource load is redirected. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. The
|request| parameter will contain the old URL and other request-related
information. The |response| parameter will contain the response that
resulted in the redirect. The |new_url| parameter will contain the new URL
and can be changed if desired. The |request| and |response| objects cannot
be modified in this callback.

:on-resource-response (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse]) -> int
Called on the IO thread when a resource response is received. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. To allow the
resource load to proceed without modification return false (0). To redirect
or retry the resource load optionally modify |request| and return true (1).
Modification of the request URL will be treated as a redirect. Requests
handled using the default network loader cannot be redirected in this
callback. The |response| object cannot be modified in this callback.
WARNING: Redirecting using this function is deprecated. Use
OnBeforeResourceLoad or GetResourceHandler to perform redirects.

:get-resource-response-filter (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse]) -> CefResponseFilter
Called on the IO thread to optionally filter resource response content. The
|browser| and |frame| values represent the source of the request, and may
be NULL for requests originating from service workers or cef_urlrequest_t.
|request| and |response| represent the request and response respectively
and cannot be modified in this callback.

:on-resource-load-complete (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,CefResponse,int,long]) -> void
Called on the IO thread when a resource load has completed. The |browser|
and |frame| values represent the source of the request, and may be NULL for
requests originating from service workers or cef_urlrequest_t. |request|
and |response| represent the request and response respectively and cannot
be modified in this callback. |status| indicates the load completion
status. |received_content_length| is the number of response bytes actually
read. This function will be called for all requests, including requests
that are aborted due to CEF shutdown or destruction of the associated
browser. In cases where the associated browser is destroyed this callback
may arrive after the cef_life_span_handler_t::OnBeforeClose callback for
that browser. The cef_frame_t::IsValid function can be used to test for
this situation, and care should be taken not to call |browser| or |frame|
functions that modify state (like LoadURL, SendProcessMessage, etc.) if the
frame is invalid.

:on-protocol-execution (fn [CefResourceRequestHandler,CefBrowser,CefFrame,CefRequest,Pointer]) -> void
Called on the IO thread to handle requests for URLs with an unknown
protocol component. The |browser| and |frame| values represent the source
of the request, and may be NULL for requests originating from service
workers or cef_urlrequest_t. |request| cannot be modified in this callback.
Set |allow_os_execution| to true (1) to attempt execution via the
registered OS protocol handler, if any. SECURITY WARNING: YOU SHOULD USE
THIS METHOD TO ENFORCE RESTRICTIONS BASED ON SCHEME, HOST OR OTHER URL
ANALYSIS BEFORE ALLOWING OS EXECUTION.

Merge properties of a CefResponseFilter
Implement this structure to filter resource response content. The functions
of this structure will be called on the browser process IO thread.

:init-filter (fn [CefResponseFilter]) -> int
Initialize the response filter. Will only be called a single time. The
filter will not be installed if this function returns false (0).

:filter (fn [CefResponseFilter,Pointer,SizeT,Pointer,Pointer,SizeT,Pointer]) -> int
Called to filter a chunk of data. Expected usage is as follows:
A. Read input data from |data_in| and set |data_in_read| to the number of
bytes that were read up to a maximum of |data_in_size|. |data_in| will
be NULL if |data_in_size| is zero.
B. Write filtered output data to |data_out| and set |data_out_written| to
the number of bytes that were written up to a maximum of
|data_out_size|. If no output data was written then all data must be
read from |data_in| (user must set |data_in_read| = |data_in_size|).
C. Return RESPONSE_FILTER_DONE if all output data was written or
RESPONSE_FILTER_NEED_MORE_DATA if output data is still pending.
This function will be called repeatedly until the input buffer has been
fully read (user sets |data_in_read| = |data_in_size|) and there is no more
input data to filter (the resource response is complete). This function may
then be called an additional time with an NULL input buffer if the user
filled the output buffer (set |data_out_written| = |data_out_size|) and
returned RESPONSE_FILTER_NEED_MORE_DATA to indicate that output data is
still pending.
Calls to this function will stop when one of the following conditions is
met:
A. There is no more input data to filter (the resource response is
complete) and the user sets |data_out_written| = 0 or returns
RESPONSE_FILTER_DONE to indicate that all data has been written, or;
B. The user returns RESPONSE_FILTER_ERROR to indicate an error.
Do not keep a reference to the buffers passed to this function.

integrated into an existing application message loop (see additional
comments and warnings on CefDoMessageLoopWork). Enabling this option is not
recommended for most users; leave this option disabled and use either the
CefRunMessageLoop() function or multi_threaded_message_loop if possible.

:windowless-rendering-enabled int

is the name of the main app executable. Also configurable using the
"log-file" command-line switch.

:log-severity cef_log_severity_t
The log severity. Only messages of this severity level or higher will be
logged. When set to DISABLE no messages will be written to the log file,
but FATAL messages will still be output to stderr. Also configurable using
the "log-severity" command-line switch with a value of "verbose", "info",
"warning", "error", "fatal" or "disable".

individual CefRequestContext instances via the
CefRequestContextSettings.ignore_certificate_errors value.

:background-color cef_color_t
Background color used for the browser before a document is loaded and when
no document color is specified. The alpha component must be either fully
opaque (0xFF) or fully transparent (0x00). If the alpha component is fully
opaque then the RGB components will be used as the background color. If the
alpha component is fully transparent for a windowed browser then the
default value of opaque white be used. If the alpha component is fully
transparent for a windowless (off-screen) browser then transparent painting
will be enabled.

:accept-language-list cef_string_t
Comma delimited ordered list of language codes without any whitespace that
will be used in the "Accept-Language" HTTP header. May be overridden on a
per-browser basis using the CefBrowserSettings.accept_language_list value.

providing an appropriate |dtor| implementation that will free the string in
the same memory space. When reusing an existing string structure make sure
to call |dtor| for the old value before assigning new |str| and |dtor|
values. Static strings will have a NULL |dtor| value. Using the below
functions if you want this managed for you.

Merge properties of a CefTask
Implement this structure for asynchronous task execution. If the task is
posted successfully and if the associated message loop is still running then
the execute() function will be called on the target thread. If the task fails
to post then the task object may be destroyed on the source thread instead of
the target thread. For this reason be cautious when performing work in the
task object destructor.

|isProxy| indicates whether the host is a proxy server. |host| contains the
hostname and |port| contains the port number. Return true (1) to continue
the request and call cef_auth_callback_t::cont() when the authentication
information is available. If the request has an associated browser/frame
then returning false (0) will result in a call to GetAuthCredentials on the
cef_request_handler_t associated with that browser, if any. Otherwise,
returning false (0) will cancel the request immediately. This function will
only be called for requests initiated from the browser process.

Merge properties of a CefV8accessor
