The callback function for the certain signal. Typically, callback function

takes on three parameters. The <parameter>service</parameter> parameter's

identifier being the first, <parameter>action</parameter> parameter's

identifier (in case GUPNP_SIGNAL_ACTION_INVOKED signal) or
|
|
<parameter>error</parameter> parameter's message (in case GUPNP_SIGNAL_NOTIFY_FAILED
|
|
signal) being the second, and the <parameter>arg</parameter> is third.
