CefBrowserHostTryCloseBrowser Method

Helper for closing a browser. Call this method from the top-level window close handler. Internally this calls CloseBrowser(false) if the close has not yet been initiated. This method returns false while the close is pending and true after the close has completed. See CloseBrowser() and CefLifeSpanHandler::DoClose() documentation for additional usage information. This method must be called on the browser process UI thread.
