gVolumeMonitorAdoptOrphanMount: gVolumeMonitorAdoptOrphanMount
Description
This function should be called by any GVolumeMonitor
implementation when a new GMount object is created that is not
associated with a GVolume object. It must be called just before
emitting the mount.added signal.
WARNING: g_volume_monitor_adopt_orphan_mount has been deprecated since version 2.20 and should not be used in newly-written code. Instead of using this function, GVolumeMonitor
implementations should instead create shadow mounts with the URI of
the mount they intend to adopt. See the proxy volume monitor in
gvfs for an example of this. Also see gMountIsShadowed,
gMountShadow and gMountUnshadow functions.
Usage
gVolumeMonitorAdoptOrphanMount(mount)
Arguments
mount
a GMount object to find a parent for Value
GVolume] the GVolume object that is the parent for mount or NULL
if no wants to adopt the GMount.
Details
If the return value is not NULL, the caller must associate the
returned GVolume object with the GMount. This involves returning
it in its gMountGetVolume implementation. The caller must
also listen for the "removed" signal on the returned object
and give up its reference when handling that signal
Similary, if implementing gVolumeMonitorAdoptOrphanMount,
the implementor must take a reference to mount and return it in
its gVolumeGetMount implemented. Also, the implementor must
listen for the "unmounted" signal on mount and give up its
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 its own GMount object that needs to be
assoicated with the GVolume object that represents the volume.
The other is for implementing a GVolumeMonitor whose sole purpose
is to return GVolume objects representing entries in the users
"favorite servers" list or similar.
