In cast 4, will GLE always be 0 -
Yesse.
even if the other end has for example reset rather than disconnected gracefully?
No... don't think so.
The problem we face here is that although we can empirically find the
GLE values for our current platforms, the possible GLE values are not
documented!
It's a bit like that, however write a few simple socket programmes and
you'll quickly learn the win32/IOCP lingua franca, there's about a zillion
examples over on koders.com, in fact probably the hardest thing about
IOCPs is remembering how to spell "queued".
so we can't be certain we've got it right, that there are
no unusual cases we simply haven't seen, or that it won't change in the
future.
I'm happy to with this now, however, since it seems basically
reasonable, although I do wonder at GLE being 0 for both a reset and a
graceful disconnect!
Are you 100% sure that's the case?
Thankyou for your help, Kevin.
No worries, but I'm not Kevin.
