NAME

       PAPI_accum -

       Accumulate and reset counters in an EventSet.

SYNOPSIS

Detailed 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
       *
