+ * %EGG_DESKTOP_FILE_LAUNCH_DIRECTORY: (char *dir)
+ * causes the application to be launched in the given directory
+ * %EGG_DESKTOP_FILE_LAUNCH_TIME: (guint32 launch_time)
+ * sets the "launch time" for the application. If the user
+ * interacts with another window after @launch_time but before
+ * the launched application creates its first window, the window
+ * manager may choose to not give focus to the new application.
+ * Passing 0 for @launch_time will explicitly request that the

+ * Sets additional #GSpawnFlags to use. See g_spawn_async() for
+ * more details.
+ * %EGG_DESKTOP_FILE_LAUNCH_SETUP_FUNC (GSpawnChildSetupFunc, gpointer)
+ * Sets the child setup callback and the data to pass to it.
+ * (See g_spawn_async() for more details.)
+ *
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_PID (GPid **pid)
+ * On a successful launch, sets *@pid to the PID of the launched
+ * application.
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STARTUP_ID (char **startup_id)
+ * On a successful launch, sets *@startup_id to the Startup
+ * Notification "startup id" of the launched application.
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STDIN_PIPE (int *fd)
+ * On a successful launch, sets *@fd to the file descriptor of
+ * a pipe connected to the application's stdin.
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STDOUT_PIPE (int *fd)
+ * On a successful launch, sets *@fd to the file descriptor of

+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STDERR_PIPE (int *fd)
+ * On a successful launch, sets *@fd to the file descriptor of

+ * The options should be terminated with a single %NULL.
+ *
+ * If @documents contains multiple documents, but

+ *
+ * For details on the Windows XP logout process, see:
+ * http://msdn.microsoft.com/en-us/library/aa376876.aspx.
+ *
+ * Vista adds some new APIs which EggSMClient does not make use of; see
+ * http://msdn.microsoft.com/en-us/library/ms700677(VS.85).aspx
+ *
+ * When shutting down, Windows sends every top-level window a
+ * WM_QUERYENDSESSION event, which the application must respond to
+ * synchronously, saying whether or not it will quit. To avoid main
+ * loop re-entrancy problems (and to avoid having to muck about too
+ * much with the guts of the gdk-win32 main loop), we watch for this
+ * event in a separate thread, which then signals the main thread and
+ * waits for the main thread to handle the event. Since we don't want
+ * to require g_thread_init() to be called, we do this all using
+ * Windows-specific thread methods.
+ *
+ * After the application handles the WM_QUERYENDSESSION event,
+ * Windows then sends it a WM_ENDSESSION event with a TRUE or FALSE
+ * parameter indicating whether the session is or is not actually
+ * going to end now. We handle this from the other thread as well.
+ *
+ * As mentioned above, Vista introduces several additional new APIs
+ * that don't fit into the (current) EggSMClient API. Windows also has
+ * an entirely separate shutdown-notification scheme for non-GUI apps,
+ * which we also don't handle here.
