NAME

       PAPI_get_overflow_event_index -

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

SYNOPSIS

Detailed Description

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

       Return values:
           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.
           PAPI_ENOEVST The EventSet specified does not exist.

       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=%#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]);}
