Unix programming question -resolved

[Jerry A Clabaugh]

Yes, I was confused about fd's versus streams, thanks.

Actually, I found everything I needed in the place I should have 
looked in the first place -' Advanced Programming in the UNIX
Environment', W. Richard Stevens.  I discovered that what I
was trying to do is called a 'coprocess', and that using
pipes is defeated by buffering problems, and that the solution
is to use pseudo-terminals.  (In case anyone wanted to know)

But this book has quite a lot of information I couldn't find
anywhere else.
