You're asking about x86 assembly language, not C, so you're not likely
to get help here.  I'm not sure whether there's a newsgroup where your
question would be on-topic.  (comp.lang.asm.x86 appears to be dead.)

There are no other active Usenet groups unfortunately.  At least I don't
know any.

You might consider posting on Stack Overflow.

That's no fun :/

I discovered Usenet a week ago, started using it, and I'm loving it.  You
can say that I am one of those people who love retro-computing.  Usenet
is much more fun to use than web forums or things like that.
