The <a class="link" href="class-giovolume.html" title="gio.Volume"><code class="classname">gio.Volume</code></a>
interface represents user-visible objects that can be mounted. Note, when porting
from GnomeVFS, <a class="link" href="class-giovolume.html" title="gio.Volume"><code class="classname">gio.Volume</code></a>
is the moral equivalent of GnomeVFSDrive.
</p><p>
Mounting a <a class="link" href="class-giovolume.html" title="gio.Volume"><code class="classname">gio.Volume</code></a>
instance is an asynchronous operation. For more information about asynchronous operations.
To mount a <a class="link" href="class-giovolume.html" title="gio.Volume"><code class="classname">gio.Volume</code></a>, first call
<code class="methodname"><a class="link" href="class-giovolume.html#method-giovolume--mount" title="gio.Volume.mount">gio.Volume.mount</a></code>()
with (at least) the <a class="link" href="class-giovolume.html" title="gio.Volume"><code class="classname">gio.Volume</code></a>
instance, optionally a
<a class="link" href="class-giomountoperation.html" title="gio.MountOperation"><code class="classname">gio.MountOperation</code></a>
object and a GAsyncReadyCallback.
</p><p>
Typically, one will only want to pass <code class="literal">None</code> 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.
</p><p>
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
<code class="methodname"><a class="link" href="class-giovolume.html#method-giovolume--mount-finish" title="gio.Volume.mount_finish">gio.Volume.mount_finish</a></code>()
with the GVolume instance and the GAsyncReady data to see if the operation was completed
successfully. If an error is present when
<code class="methodname"><a class="link" href="class-giovolume.html#method-giovolume--mount-finish" title="gio.Volume.mount_finish">gio.Volume.mount_finish</a></code>()
is called, then it will be filled with any error information.
</p><p>
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 predefind strings
as names for the different kinds of identifiers:
"hal-udi", "label", etc. Use
<code class="methodname"><a class="link" href="class-giovolume.html#method-giovolume--get-identifier" title="gio.Volume.get_identifier">gio.Volume.get_identifier</a></code>()
to obtain an identifier for a volume.
