39 * @short_description: mount management
41 * The #GMount interface represents user-visible mounts. Note, when
42 * porting from GnomeVFS, #GMount is the moral equivalent of
45 * Unmounting a #GMount instance is an asynchronous operation. For
46 * more information about asynchronous operations, see #GAsyncReady
47 * and #GSimpleAsyncReady. To unmount a #GMount instance, first call
48 * g_mount_unmount() with (at least) the #GMount instance and a
49 * #GAsyncReadyCallback. The callback will be fired when the
50 * operation has resolved (either with success or failure), and a
51 * #GAsyncReady structure will be passed to the callback. That
52 * callback should then call g_mount_unmount_finish() with the #GMount
53 * and the #GAsyncReady data to see if the operation was completed
54 * successfully. If an @error is present when
55 * g_mount_unmount_finish() is called, then it will be filled with any
