In that case, I'd like to request of Walter that this be changed. Otherwise, all of my code which uses getopt will have to do lots of ugly error checking of the return code. Moreover, if it fails, there's no obvious way to find out why it failed, wheras an exception could carry that information. | ||||||||||||||||
