PAPI_accum(3) PAPI PAPI_accum(3)NAMEPAPI_accum - Accumulate and reset counters in an EventSet.SYNOPSISDetailed Description @par C Interface: int PAPI_accum( int EventSet, long_long * values ); These calls assume an initialized PAPI library and a properly added event set. PAPI_accum adds the counters of the indicated event set into the array values. The counters are zeroed and continue counting after the operation. Note the differences between PAPI_read and PAPI_accum, specifically that PAPI_accum resets the values array to zero. @param EventSet an integer handle for a PAPI Event Set as created by PAPI_create_eventset @param *values an array to hold the counter values of the counting events @retval PAPI_EINVAL One or more of the arguments is invalid. @retval PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable. @retval PAPI_ENOEVST The event set specified does not exist. @par Examples: * do_100events( ); * if ( PAPI_read( EventSet, values) != PAPI_OK ) * handle_error( 1 ); * // values[0] now equals 100 * do_100events( ); * if (PAPI_accum( EventSet, values ) != PAPI_OK ) * handle_error( 1 ); * // values[0] now equals 200 * values[0] = -100; * do_100events( ); * if (PAPI_accum( EventSet, values ) != PAPI_OK ) * handle_error( 1 ); * // values[0] now equals 0 * See Also: PAPIF_accum PAPI_start PAPI_set_opt PAPI_reset Author Generated automatically by Doxygen for PAPI from the source code.
