So for each connection you need to have something queued at all times. I just went looking for the code and it appears i lost it with a HD crash.

If there are any windows programmers here, I can again point people at working IOCP
event management code. This code is interfaced to a different project so can't
be used as written but should be indicative. This link:


points to IOCP based event management from my project. This
does socket I/O:


and this is the IOCP based event management:


There's also code for timer events, and a weird thing called a self-piper,
which is used for pipes. You should be able to "click through" any #include
files to see them too.

I did not write this code. I cannot compile or build this code.
