			It has the following prototype:
			void callback_func(unsigned int secs,
					   unsigned int nanos,
					   void *edp,
					   void *callback_data)
                               "secs" the time_t of notification
                               "nanos" is the nanosecs into secs of notification
				"edp" Event Display Packet (EDP) containing
				      the contents of the message
				"callback_data" is the pointer to user
						supplied data
