Just as a follow-up, here is the DJGPP info page on the pipe function:

pipe
====

Syntax
------

     #include <unistd.h>
     
     int pipe(int fildes[2]);

Description
-----------

This function is provided only to assist in porting from Unix. It
always returns an error condition.

Portability
-----------

not ANSI, POSIX
