I'd probably do it this way if the method was private to the module; 
with the struct passed in by reference thereby passing any memory 
management issues onto the caller, i.e. it could be stack allocated or 
malloc'd

Otherwise if it was a public method, it follow the -get... convention 
returning both parameters by reference.
