True, I'd forgotten.

The likelihood of the OP having a C2011 implementation to hand seems
fairly low, though.

You missed Noob's point.

Your question looks very much like you're asking us to do your homework
for you. You haven't shown us any of your own efforts to solve the
problems; you've just presented the assigned questions and asked for
help. In other words, you appear to be trying to cheat by getting other
people to do your work for you, so that you can turn it in to your
instructor and take credit as if you'd done it yourself.

He wasn't expecting you to take him up on his offer; he was making a
point about who should get credit for the work.

You said later that this isn't class work, but that was not at all
obvious from your original post.

But even if you're studying on your own, asking for help here without
*any* effort to solve the problem yourself is not a good way to learn.
Try to come up with your own solution, and let us know if you have
questions about code that *you've written*, and we'll be happy to help
if we can.

What did you learn from Eric's program? Please review Keith's and
Rich's follow-ups to your reply to James' post.

What he's learned thus far is as nothing compared to what he'll
learn when he gives my program to his professor ...

Doing a test run will be a learning experience too, but for best results
he should put that off until after he's turned it in.

He did say elsewhere in this thread that he's studying on his own from a
book, not doing homework for a class.

My hunch is that he knows little Latin, so even if someone
said "pri memo dulus" to him he wouldn't understand.

This is trivial in C for a common memory buffer of known length
to the two threads to be locked by the writer for bytes written, and to be read by another thread.
