Assuming that they disagreed, an ANSI C application would expect the ANSI behavior, and a POSIX application would expect the POSIX behavior. How you tell which you are? Simple! If you use extensions of POSIX, you're POSIX. But since they agree, it's a moot point. :) -s -- Peter Seebach - seebs@solon.com - Copyright 1996 Peter Seebach. C/Unix wizard -- C/Unix questions?
