Thanks very much. Sorta got things almost working, but still confused
abut threading/forking/non-blocking issues (2-year programming degrees
don't go into the multi-processing stuff so I'm supplementing with
online lectures from MIT, arsdigita, etc. Feedback isn't a forte with
passive web lectures however).
I've new hurdles to get over, including the non-blocking design, and how
to make sure my packed stream method doesn't pad my UDP packets with
zeros at the end but that latter is purely a mechanical detail to trace
through.
Thanks again.
