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_assign_eventset_component -

       Assign a component index to an existing but empty EventSet.

SYNOPSIS

Detailed Description
       @par C Interface:
       PAPI_assign_eventset_component( int  EventSet, int  cidx );

       @param EventSet
	   An integer identifier for an existing EventSet.
       @param cidx
	   An integer identifier for a component.
	   By convention, component 0 is always the cpu component.

       @retval PAPI_ENOCMP
	   The argument cidx is not a valid component.
       @retval PAPI_ENOEVST
	   The EventSet doesn't exist.
       @retval PAPI_ENOMEM
	   Insufficient memory to complete the operation.

       PAPI_assign_eventset_component assigns a specific component index,
       as specified by cidx, to a new EventSet identified by EventSet, as obtained
       from PAPI_create_eventset. EventSets are ordinarily automatically bound
       to components when the first event is added. This routine is useful to
       explicitly bind an EventSet to a component before setting component related
       options.

       @par Examples:

       *   int EventSet = PAPI_NULL;
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Bind our EventSet to the cpu component
       *   if ( PAPI_assign_eventset_component( EventSet, 0 ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Convert our EventSet to multiplexing
       *   if ( PAPI_set_multiplex( EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *
