It sounds to me like he means raising a C++ exception with the throw
statement.  People tend to say 'C' when they mean 'C++', it causes a
lot of confusion.

Anyway, Vinco, I think the answer is that the C++ and python exception
mechanisms are totally different animals; python doesn't support C++
exceptions.  This is pretty much inevitable since python is written in
C.  Besides, C++ exceptions are really language-specific; it would
make it impossible to raise exceptions in other languages.

So what you'll have to do is catch your exception, set the global
value, and return a NULL (0) from your method.  Of course, if you want
to extend python to catch C++ exceptions, I'm sure many people would
appreciate it. :)
