int PAPI_reset( int EventSet );
.RE

\fBParameters\fP
.RS 4
\fIEventSet\fP an integer handle for a PAPI event set as created by \fBPAPI_create_eventset\fP
.RE
.PP
\fBReturn values\fP
.RS 4
\fIPAPI_OK\fP
.br
\fIPAPI_ESYS\fP A system or C library call failed inside PAPI, see the errno variable\&.
.br
\fIPAPI_ENOEVST\fP The EventSet specified does not exist\&.
.RE

PAPI_reset() zeroes the values of the counters contained in EventSet\&. This call assumes an initialized PAPI library and a properly added event set
.PP
\fBExample:\fP
.RS 4
.PP
.nf
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);
