PAPI_accum - Accumulate and reset counters in an EventSet.

       Generated automatically by Doxygen for PAPI from the source code.

Version 7.1.0.0                                  Thu Dec 14 2023                                   PAPI_accum(3)

CInterface:
           #include <papi.h>
           int PAPI_accum(intEventSet,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.

       ParametersEventSet an integer handle for a PAPI Event Set as created by PAPI_create_eventset*values an array to hold the counter values of the counting events

       ReturnvaluesPAPI_EINVAL One or more of the arguments is invalid.
           PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable.
           PAPI_ENOEVST The event set specified does not exist.

       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
