Gets the activation root for a #GVolume if it is known ahead of
mount time. Returns %NULL otherwise. If not %NULL and if @volume
is mounted, then the result of g_mount_get_root() on the
#GMount object obtained from g_volume_get_mount() will always
either be equal or a prefix of what this function returns. In
other words, in code
mount = g_volume_get_mount (volume); // mounted, so never NULL
mount_root = g_mount_get_root (mount);
volume_activation_root = g_volume_get_activation_root (volume); // assume not NULL
]|
then the expression
|[<!-- language="C" -->
(g_file_has_prefix (volume_activation_root, mount_root) ||
g_file_equal (volume_activation_root, mount_root))
]|
will always be %TRUE.
Activation roots are typically used in #GVolumeMonitor
implementations to find the underlying mount to shadow, see
g_mount_is_shadowed() for more details.
