It isn't really an exception but I use the idiom of returning an
(int,string) tuple:

  (err,error_message)

If err != 0, it's interpreted as an error code.  A successful return
is (0,"").

I don't happen to do it, but I suppose you could then raise an
exception on the client size by hand when non-zero is returned.
