NAME

PAPI_stop -
Stop counting hardware events in an event set.

SYNOPSIS

Detailed Description

C Interface:
#include <papi.h>
 

int PAPI_stop( int EventSet, long long * values );
Parameters:
EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset
 
values -- an array to hold the counter values of the counting events
Return values:
PAPI_OK
 
PAPI_EINVAL One or more of the arguments is invalid.
 
PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable.
 
PAPI_ENOEVST The EventSet specified does not exist.
 
PAPI_ENOTRUN The EventSet is currently not running.
PAPI_stop halts the counting of a previously defined event set and the counter values contained in that EventSet are copied into the values array Assumes an initialized PAPI library and a properly added event set.
Example: 
*  int EventSet = PAPI_NULL;
*  long long values[2];
*  int ret;
*  
*  ret = PAPI_create_eventset(&EventSet);
*  if (ret != PAPI_OK) handle_error(ret);
*  
*  // Add Total Instructions Executed to our EventSet
*  ret = PAPI_add_event(EventSet, PAPI_TOT_INS);
*  if (ret != PAPI_OK) handle_error(ret);
*  
*  // Start counting
*  ret = PAPI_start(EventSet);
*  if (ret != PAPI_OK) handle_error(ret);
*  poorly_tuned_function();
*  ret = PAPI_stop(EventSet, values);
*  if (ret != PAPI_OK) handle_error(ret);
*  printf("%lld\n",values[0]);
