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 );
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_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);
