[ Version ( deprecated = true ) ]
public uint self_handle { get; }
Warning: self_handle is deprecated.
The CONTACT handle of the local user on this connection, or 0 if we don't know yet or if the connection has become invalid.
Use self_contact instead.
This may change if the local user's unique identifier changes (for instance by using /nick on IRC), in which case notify will be emitted.
To wait for a valid self-handle (and other properties), call
prepare_async with the feature TP_CONNECTION_FEATURE_CONNECTED.
