get_identifier
Description:
This channel's associated identifier, or the empty string if no identifier or unknown.
This is the same as the identifier property, and isn't
guaranteed to be set until the TP_CHANNEL_FEATURE_CORE property is ready.
Changed in 0.11.4: as with identifier, this could
previously either be null or the empty string if there was no suitable value. It is now non-%NULL in all cases.
Parameters:
| this |
a channel |
Returns:
|
the identifier |
