Finds a G::Volume object by it's UUID (see g_volume_get_uuid()).
- Parameters:
-
uuid The UUID to look for.
- Returns:
- A G::Volume or
0
if no such volume is available.
Glib::RefPtr<Mount> Gio::VolumeMonitor::get_mount_for_uuid | ( | const std::string & | uuid | ) |
Finds a G::Mount object by it's UUID (see g_mount_get_uuid()).
- Parameters:
-
uuid The UUID to look for.
- Returns:
- A G::Mount or
0
if no such mount is available.
static Glib::RefPtr<Volume> Gio::VolumeMonitor::adopt_orphan_mount | ( | const Glib::RefPtr<Mount>& | mount | ) | [static] |
This function should be called by any G::VolumeMonitor implementation when a new G::Mount object is created that is not associated with a G::Volume object.
It must be called just before emitting the mount_added signal.
If the return value is not 0
, the caller must associate the returned G::Volume object with the G::Mount. This involves returning it in it's g_mount_get_volume() implementation. The caller must also listen for the "removed" signal on the returned object and give up it's reference when handling that signal
Similary, if implementing g_volume_monitor_adopt_orphan_mount(), the implementor must take a reference to mount and return it in it's g_volume_get_mount() implemented. Also, the implementor must listen for the "unmounted" signal on mount and give up it's reference upon handling that signal.
There are two main use cases for this function.
One is when implementing a user space file system driver that reads blocks of a block device that is already represented by the native volume monitor (for example a CD Audio file system driver). Such a driver will generate it's own G::Mount object that needs to be assoicated with the G::Volume object that represents the volume.
The other is for implementing a G::VolumeMonitor whose sole purpose is to return G::Volume objects representing entries in the users "favorite servers" list or similar.
- Parameters:
-
mount A G::Mount object to find a parent for.
- Returns:
- The G::Volume object that is the parent for mount or
0
if no wants to adopt the G::Mount.
Friends And Related Function Documentation
Glib::RefPtr<Gio::VolumeMonitor> wrap | ( | GVolumeMonitor * | object, | |
bool | take_copy = false | |||
) | [related] |
A Glib::wrap() method for this object.
- Parameters:
-
object The C instance. take_copy False if the result should take ownership of the C instance. True if it should take a new copy or ref.
- Returns:
- A C++ instance that wraps this C instance.
