Yep. As a matter of fact, they can. :-)

BTW, does anyone have a favorite free "exceptions" library for C?
We could roll our own of course, but if one is already available, why?

I saw one in a library called Kazlib on freshmeat. Its syntax isn't as
simple as using a language which has a built-in "try", "catch", and
"raise" semantics, but I don't know how fancy you could get with
the C preprocessor to make something like that happen.
