NAME

       PAPI_get_overflow_event_index -

       converts an overflow vector into an array of indexes to overflowing events

SYNOPSIS

Detailed Description
       @param EventSet
	   an integer handle to a PAPI event set as created by PAPI_create_eventset
       @param overflow_vector
	   a vector with bits set for each counter that overflowed.
	   This vector is passed by the system to the overflow handler routine.
       @param *array
	   an array of indexes for events in EventSet.
	   No more than *number indexes will be stored into the array.
       @param *number
	   On input the variable determines the size of the array.
	   On output the variable contains the number of indexes in the array.

       @retval PAPI_EINVAL
	   One or more of the arguments is invalid. This could occur if the overflow_vector is empty (zero), if the array or number pointers are NULL, if the value of number is less than one, or if the EventSet is empty.
       @retval PAPI_ENOEVST
       The EventSet specified does not exist.
       @par Examples

	       void handler(int EventSet, void *address, long_long overflow_vector, void *context){
	       int Events[4], number, i;
	       int total = 0, retval;
	       printf("Overflow #%d Handler(%d) Overflow at %p! vector=0x%llx0,
	       total, EventSet, address, overflow_vector);
	       total++;
	       number = 4;
	       retval = PAPI_get_overflow_event_index(EventSet,
	       overflow_vector, Events, &number);
	       if(retval == PAPI_OK)
	       for(i=0; i<number; i++) printf("Event index[%d] = %d", i, Events[i]);}

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
       *
