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.
BTW, I know C spec well.

It is a basic part of the C language specification - variables declared
at file scope are implicitly initialized to zero. Perhaps you need to
study the language a bit more before trying to do any more work in it.
