Reset the hardware event counts in an event set. More...

Detailed Description

C Prototype:: #include <papi.h>
int PAPI_reset( int EventSet );

Parameters:

EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset

Return values:

PAPI_OK
PAPI_ESYS	A system or C library call failed inside PAPI, see the errno variable.
PAPI_ENOEVST	The EventSet specified does not exist.

PAPI_reset() zeroes the values of the counters contained in EventSet. This call assumes an initialized PAPI library and a properly added event set

Example:

int EventSet = PAPI_NULL;
int Events[] = {PAPI_TOT_INS, PAPI_FP_OPS};
int ret;
 
// Create an empty EventSet
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);

// Add two events to our EventSet
ret = PAPI_add_events(EventSet, Events, 2);
if (ret != PAPI_OK) handle_error(ret);

// Start counting
ret = PAPI_start(EventSet);
if (ret != PAPI_OK) handle_error(ret);

// Stop counting, ignore values
ret = PAPI_stop(EventSet, NULL);
if (ret != PAPI_OK) handle_error(ret);

// reset the counters in this EventSet
ret = PAPI_reset(EventSet);
if (ret != PAPI_OK) handle_error(ret);
