Stop counting hardware events and reset values to zero. More...

Detailed Description

C Interface:: #include <papi.h>
int PAPI_stop_counters( long long *values, int array_len );

Parameters

*values	an array where to put the counter values
array_len	the number of items in the *values array

Postcondition: After this function is called, the values are reset to zero.

Return values

PAPI_EINVAL	One or more of the arguments is invalid.
PAPI_ENOTRUN	The EventSet is not started yet.
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().

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