If a filedescriptor is given to one of these macros that is too large,
I'd consider that a programming error. Another problem is, that
there's no return value, so all you're adding is a silent failure mode.

This is about the same case as "should we check for NULL pointers in
things like fprintf" in my opinion. I don't think it's a good idea.
