getActivationRoot

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

|[ GMount *mount; GFile *mount_root GFile *volume_activation_root;

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 | (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.
