/**
 * The #GVolume interface represents user-visible objects that can be
 * mounted. Note, when porting from GnomeVFS, #GVolume is the moral
 * equivalent of #GnomeVFSDrive.
 * 
 * Mounting a #GVolume instance is an asynchronous operation. For more
 * information about asynchronous operations, see #GAsyncResult and
 * #GTask. To mount a #GVolume, first call g_volume_mount() with (at
 * least) the #GVolume instance, optionally a #GMountOperation object
 * and a #GAsyncReadyCallback.
 * 
 * Typically, one will only want to pass %NULL for the
 * #GMountOperation if automounting all volumes when a desktop session
 * starts since it's not desirable to put up a lot of dialogs asking
 * for credentials.
 * 
 * The callback will be fired when the operation has resolved (either
 * with success or failure), and a #GAsyncReady structure will be
 * passed to the callback.  That callback should then call
 * g_volume_mount_finish() with the #GVolume instance and the
 * #GAsyncReady data to see if the operation was completed
 * successfully.  If an @error is present when g_volume_mount_finish()
 * is called, then it will be filled with any error information.
 * 
 * ## Volume Identifiers # {#volume-identifier}
 * 
 * It is sometimes necessary to directly access the underlying
 * operating system object behind a volume (e.g. for passing a volume
 * to an application via the commandline). For this purpose, GIO
 * allows to obtain an 'identifier' for the volume. There can be
 * different kinds of identifiers, such as Hal UDIs, filesystem labels,
 * traditional Unix devices (e.g. `/dev/sda2`), UUIDs. GIO uses predefined
 * strings as names for the different kinds of identifiers:
 * #G_VOLUME_IDENTIFIER_KIND_HAL_UDI, #G_VOLUME_IDENTIFIER_KIND_LABEL, etc.
 * Use g_volume_get_identifier() to obtain an identifier for a volume.
 * 
 * 
 * Note that #G_VOLUME_IDENTIFIER_KIND_HAL_UDI will only be available
 * when the gvfs hal volume monitor is in use. Other volume monitors
 * will generally be able to provide the #G_VOLUME_IDENTIFIER_KIND_UNIX_DEVICE
 * identifier, which can be used to obtain a hal device by means of
 * libhal_manager_find_device_string_match().
