gchar* atk_plug_get_id ( AtkPlug* plug )
Gets the unique ID of an
AtkPlug object, which can be used to
embed inside of an
AtkSocket using atk_socket_embed().
Internally, this calls a class function that should be registered
by the IPC layer (usually at-spi2-atk). The implementor of an
AtkPlug object should call this function (after atk-bridge is
loaded) and pass the value to the process implementing the
AtkSocket, so it could embed the plug.
