/** The Volume interface represents user-visible objects that can be mounted.
 *
 * Mounting a Volume instance is an asynchronous operation. For more information about asynchronous operations, see AsyncReady and SimpleAsyncReady. To
 * mount a GVolume, first call mount(), optionally providing a MountOperation object and a SlotAsyncReady callback.
 *
 * Typically, you will not want to provide a MountOperation 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 AsyncReady 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 finish() is called, then it will be filled with any error information.
