Function Documentation

size_t* map_event_to_counter	(	struct op_event const *	pev[],
		int	nr_events,
		op_cpu	cpu_type
	)

Parameters:

	pev	array of selected event we want to bind to counter
	nr_events	size of pev array
	cpu_type	cpu type

Try to calculate a binding between passed event in pev and counter number. The binding is returned in a size_t * where returned ptr[i] is the counter number bound to pev[i]
