/**

|
* SECTION:gvolume
|
|
* @short_description: Volume management
|
|
* @include: gio/gio.h
|
|
*
|
|
* 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 #GAsyncReady and
|
|
* #GSimpleAsyncReady. 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.
|
|
*
|
|
* <para id="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. <filename>/dev/sda2</filename>),
|
|
* uuids. GIO uses predefind 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.
|
|
* </para>
|
|
*
|
|
* 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_manger_find_device_string_match().
