Yes, because a exception means: Some sort of error occured and this
functions threw an exception. It didn't return. The return value of
CosNaming_NamingContext_resolve is not even transmitted over the wire
back to the clienr. How should the client know it? Did you ever look at
any exception system? It _never_ returns anything, when an exception is
thrown. Indeed this is the whole idea of exceptions. To have a system to
override normal returns.

That the mapping into C does not carry over that idea very good (and
cannot do it) is another point.

Bye,
Sebastian
