This is a stupid question, but... What is wait3() and how does it differ from wait() ? Before you flame me, I have RTFM'd and text-searched the XENIX and ISC manuals to death without a hint. I can't seem to determine it's usage from the context it is used in in the program I am trying to port. -- < Alan H.

It differs from wait(S) in that it will return the status of any stopped processes (job control stop, that is). Note that since xenix doesn't have job control, there is little to no need for it. On the other hand, POSIX has a routine called 'waitpid,' which can be made into a wait3() via a macro. SCO UNIX supports it (because it has job control). -- Sean Eric Fagan | "I made the universe, but please don't blame me for it; sef@kithrup.COM | I had a bellyache at the time." -----------------+ -- The Turtle (Stephen King, _It_) Any opinions expressed are my own, and generally unpopular with others.
