This is a dilemma, because it certainly should return a NULL
result. But if you force it to, you suddenly lose a lot
of backward compatibility and the ability to write
platform independent programs.

This might be one of those IDL tattoos. You just
have to learn to live with the regret engendered
by some of the foolish things you did in your youth.

Cheers,

David
