The <a class="link" href="class-giomount.html" title="gio.Mount"><code class="classname">gio.Mount</code></a>
interface represents user-visible mounts. Note, when porting from GnomeVFS,
<a class="link" href="class-giomount.html" title="gio.Mount"><code class="classname">gio.Mount</code></a>
is the moral equivalent of GnomeVFSVolume.
</p><p>
<a class="link" href="class-giomount.html" title="gio.Mount"><code class="classname">gio.Mount</code></a>
is a "mounted" filesystem that you can access. Mounted is in quotes because
it's not the same as a unix mount, it might be a gvfs mount, but you can still
access the files on it if you use GIO. Might or might not be related to a volume object.
</p><p>
Unmounting a GMount instance is an asynchronous operation. For more information
about asynchronous operations, see GAsyncReady and GSimpleAsyncReady. To unmount
a <a class="link" href="class-giomount.html" title="gio.Mount"><code class="classname">gio.Mount</code></a> instance,
first call
g_mount_unmount()
with (at least) the GMount instance and a GAsyncReadyCallback. 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_mount_unmount_finish()
with the GMount and the GAsyncReady data to see if the operation was completed successfully.
If an error is present when g_mount_unmount_finish() is called, then it will be filled
with any error information.

The <code class="methodname">is_shadowed</code>() method determines if mount
is shadowed. Applications or libraries should avoid displaying mount
in the user interface if it is shadowed.
</p><p>
A mount is said to be shadowed if there exists one or more user visible
objects (currently
<a class="link" href="class-giomount.html" title="gio.Mount"><code class="classname">gio.Mount</code></a>
objects) with a root that is inside the root of mount.
</p><p>
One application of shadow mounts is when exposing a single file system
that is used to address several logical volumes. In this situation, a
<a class="link" href="class-giovolumemonitor.html" title="gio.VolumeMonitor"><code class="classname">gio.VolumeMonitor</code></a>
implementation would create two
<a class="link" href="class-giovolume.html" title="gio.Volume"><code class="classname">gio.Volume</code></a>
objects (for example, one for the camera functionality of the device
and one for a SD card reader on the device) with activation URIs
gphoto2://[usb:001,002]/store1/ and gphoto2://[usb:001,002]/store2/.
When the underlying mount (with root gphoto2://[usb:001,002]/) is
mounted, said
<a class="link" href="class-giovolumemonitor.html" title="gio.VolumeMonitor"><code class="classname">gio.VolumeMonitor</code></a>
implementation would create two
<a class="link" href="class-giomount.html" title="gio.Mount"><code class="classname">gio.Mount</code></a>
objects (each with their root matching the corresponding volume
activation root) that would shadow the original mount.
</p><p>
The proxy monitor in GVfs 2.26 and later, automatically creates and
manage shadow mounts (and shadows the underlying mount) if the activation
root on a <a class="link" href="class-giovolume.html" title="gio.Volume"><code class="classname">gio.Volume</code></a>
is set.
