Your claim that "The practical effect of both kinds of pipes is the
same" is inconsistent with David's claim that "what you are
describing is just moving data around within a single process". I
expected you to either make a comment that he was wrong about his claim,
or an admission that you were wrong about your claim. A third
alternative would be an explanation why you believe that the uselessness
of "informal pipes" for inter-process communication (which is the main
use I'm aware of for "formal pipes") fails to render your claim invalid.
Would you care to provide one of those three alternatives? Or suggest a
fourth?
