* 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.
