// Perform a single iteration of CEF message loop processing. This function is

// 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.
// provided for cases where the CEF message loop must be integrated into an

// 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
