@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.
