/** @class PAPI_stop_counters
 *	@brief Stop counting hardware events and reset values to zero.
 *
 *	@par C Interface:
 *	\#include <papi.h> @n
 *	int PAPI_stop_counters( long long *values, int array_len );
 *
 * @param *values
 *		an array where to put the counter values
 * @param array_len
 *		the number of items in the *values array
 *
 * @post
 *	After this function is called, the values are reset to zero.
 *
 *	@retval PAPI_EINVAL
 *		One or more of the arguments is invalid.
 *	@retval PAPI_ENOTRUN
 *		The EventSet is not started yet.
 *	@retval PAPI_ENOEVST
 *		The EventSet has not been added yet.
 *
 * The PAPI_stop_counters() function stops the counters and copies the counts
 * into the *values array.
 * The counters must have been started by a previous call to PAPI_start_counters().
