[Tutor] Exceptions vs. Status Codes

[wkranec@gmail.com]

Hi,

I have a general question regarding programming style which may or may
not have an answer.  Is it a better practice to have a function raise
an exception on error, so that the error can be caught; or return a
status code indicating that the function was unsuccessful?

Like I said, I don't expect an answer that works in general, but some
guidelines about when one approach is more appropriate would be
appreciated.

Thanks,

Bill
