beat _new_beat

(

this thread continuously checks if a function, that is registered to be called regularly using register_beat() has to be called again

Parameters:

arg	unused/ignored

void heartbeat_birth

(

start up the heartbeat

void heartbeat_death

(

void

)

stop calling hearbeat functions

void register_beat	(	int	freq,
		beathandler	f,
		void *	arg
	)

register a function to receive heartbeats
