"WSAPoll" because it's not a POSIX poll even though the signature is the same at it works similarly for sockets and I guess Microsoft thought through it better 15 years later.
But the original claim is just that select/poll are "everywhere it makes sense", but this depends on what you define select/poll to be. I think something close to POSIX is what makes sense. If you can't use it on pipes and FIFOs (and even regular files without getting an error) that seems like a pretty contrived definition.
The whole moving around of definition of what is the C standard library just because of popularity seems unproductive. ("You can do nonblocking IO using the C std library." -- no, you can't) Most popular 3rd party libraries support or can easily support the most popular targets due in large part to them being popular, that means "in practice, they exist everywhere it makes sense." Does this mean all popular 3rd party libraries are part of the C standard library?
Colloquially redefining terms like what is the C standard library just sows confusion with no benefit (as was illustrated earlier in regards to threads; C11 threads are not pthreads), just say what you mean in this case.
Yes, it is remarkable what little you actually get when you strictly stick to the actual C89/C99/C11 definitions of what's in "The C Standard Library". I still get tripped up on it, and often have to double check: Surely sigaction() is part of the C Standard! NOPE it's POSIX, but signal() is! Surely strptime() is part of the standard! NOPE, but strftime() is. termios stuff? NOPE. It's a minefield out there.
