NAME

PAPI_reset - Reset the hardware event counts in an event set.

SYNOPSIS

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);
