PAPI_stop_counters3
Stop counting hardware events and reset values to zero.
Detailed Description
@par C Interface: 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);
