PAPI_stop_counters()

This function stops the counters and returns their values. The counters must have been started by a previous call to PAPI_start_counters().

*values -- an array where to put the counter values

array_len -- the number of items in the *values array

On success, this function returns PAPI_OK.
On error, a non-zero error code is returned.

PAPI_EINVAL
	One or more of the arguments is invalid.
PAPI_ENOTRUN
	The eventset is not started yet.

  int Events[2] = { PAPI_TOT_CYC, PAPI_TOT_INS };
  long_long values[2];
  int num_hwcntrs = 0;
        
  if ((num_hwcntrs = PAPI_num_counters()) < PAPI_OK)
    handle_error(1);

  if (num_hwcntrs > 2)
    num_hwcntrs = 2;

  /* Start counting events */

  if (PAPI_start_counters(Events, num_hwcntrs) != PAPI_OK)
    handle_error(1);

  your_slow_code();

  /* Stop counting events */

  if (PAPI_stop_counters(values, num_hwcntrs) != PAPI_OK)
    handle_error(1);
