Learning C

[Scot Henderson <saintjust@xxxxxxxxxxxxx>]

Hello 
This may be a little off, but I am attempting to learn C, and I have run into a
slight problem. The book I am using refers to 5 standard streams, stdin,
stdout, stderr, stdprn, and stdaux. The problem I am having is that, from what I
have read in the man and info pages, is that only  the first three exist in
GNU/Linux. 
I would like to find out what to do to replicate these functions for
the examples in the book. The one that most concerns me is the stdprn, because
that is any program that creates a print out.
Thanks in advance, and I apologize if this is beyond the scope of this list.
