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);
