In general, I think MPI standard should be fixed/clarified in many places regarding to handling of returned references. Testing for predefined Comm a Group handling is rather easy, but for Datatypes is really cumbersome. Perhaps a MPI_Type_is_named(MPI_Datatype, int*flag) would help a lot. What do you think?
Just curious -- why do you need to know if a handle refers to a predefined object?
