Thnx.
One to remember..
Just like "#!/usr/bin/env perl"    (Why doesn't everybody uses that!)

Ok keith.
Thnx for your reply, it really helped.

I don't have an excuse for my slappy code....
After struggling, finding out how to use DLLTOOL,
and coming to the conclusion that O_NONBLOCK code
is buggy in Cygwin.
I finally motivated myself to build some UDP server & client test code.
(Borrowed some code from an old C++ project of mine..)
And that even failed, by my own human error.
Anyway.. no excuse.


I'm pretty good, mind you :-)


Anyway, I have extrapolated your sources (based on mine) to the
following.
Would you pls take a look at the server.c code?

It should, when in O_NONBLOCK mode, do some bussy waiting,
just like an awful Kernel Scheduler.

But it just isn't...
And that is the problem I also have in my Library I wanna port to CYGWIN.

I will include the sources in a .tgz.
(Mailinglist will allow attachments?)


Hope you have some spare time to look at it.

Thnx in advance.



Vriendelijke Groet,

Note: For efficiŽnt work-behaviour, I'm currently only reading my E-mail
twice a day!
