Detailed Description

@par C Interface:
\#include <papi.h> @n
int PAPI_stop_counters( long long *values, int array_len );
Parameters
*valuesan array where to put the counter values
array_lenthe number of items in the *values array

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().

int Events[2] = { PAPI_TOT_CYC, PAPI_TOT_INS };
long long values[2];
if ( PAPI_start_counters( Events, 2 ) != PAPI_OK )
handle_error(1);
if ( PAPI_stop_counters( values, 2 ) != PAPI_OK )
handle_error(1);
