+ * egg_desktop_file_launch:

+ * @documents: a list of URIs or paths to documents to open
+ * @error: error pointer
+ * @...: additional options
+ *
+ * Launches @desktop_file with the given arguments. Additional options
+ * can be specified as follows:
+ *
+ *   %EGG_DESKTOP_FILE_LAUNCH_CLEARENV: (no arguments)
+ *       clears the environment in the child process
+ *   %EGG_DESKTOP_FILE_LAUNCH_PUTENV: (char **variables)
+ *       adds the NAME=VALUE strings in the given %NULL-terminated
+ *       array to the child process's environment
+ *   %EGG_DESKTOP_FILE_LAUNCH_SCREEN: (GdkScreen *screen)
+ *       causes the application to be launched on the given screen
+ *   %EGG_DESKTOP_FILE_LAUNCH_WORKSPACE: (int workspace)
+ *       causes the application to be launched on the given workspace
+ *   %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
+ *       application not receive focus.
+ *   %EGG_DESKTOP_FILE_LAUNCH_FLAGS (GSpawnFlags flags)
+ *       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
+ *       a pipe connected to the application's stdout.
+ *   %EGG_DESKTOP_FILE_LAUNCH_RETURN_STDERR_PIPE (int *fd)
+ *       On a successful launch, sets *@fd to the file descriptor of
+ *       a pipe connected to the application's stderr.
+ *
+ * The options should be terminated with a single %NULL.
+ *
+ * If @documents contains multiple documents, but
+ * egg_desktop_file_accepts_multiple() returns %FALSE for
+ * @desktop_file, then egg_desktop_file_launch() will actually launch
+ * multiple instances of the application. In that case, the return
+ * value (as well as any values passed via
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_PID, etc) will only reflect the
+ * first instance of the application that was launched (but the
+ * %EGG_DESKTOP_FILE_LAUNCH_SETUP_FUNC will be called for each
+ * instance).
+ *
+ * Return value: %TRUE if the application was successfully launched.
