PAPI_reset man page

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

Detailed Description

C Prototype:

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


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

Return values:

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 

@par 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);
