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]);}
