Yes. but funny that you invoked FD_ZERO() for sd_readers and sd_writers. You are assuming the semantics of FD_ZERO() is to "set something as zero", but on some system it is not. For example, implement fd_set as an array, then 0 is a valid value. FD_ZERO() have to initialize something as -1 ... Funny that the code treat sd_actives differently.

That's a different question than you asked at first.

BTW, I know C spec well.

Then you should know your original question has no dependency on the compiler being used. Rather than waste people's time, you should ask your actual question at the outset, not some meaningless one.
