 AC> Hi, Ronald.

-=> Ronald Van Iwaarden spaketh unto Andrew Clegg <=-

 RVI> If you now do a fork(), exec() call, then you can have a second
 RVI> program that inherits this pipe from the parent.

 AC> Let me just make sure I understand this properly:

 AC> 1. Call pipe() to create an anonymous, two-channel pipe.
 AC> 2. Call fork() to produce a second copy of the program.
 AC> 3. Call one of the exec* functions to replace copy #2 of the
 AC> original program with the new program.
 AC> 4. Copy #1 of the original program, and the new program,
 AC> will now be connected via the pipe.

 AC> Is that right?

Exactly!  fork() and exec() are not efficient under OS/2 (there are some
significant restrictions regarding multithreaded programs for fork()) but
they will make more portable code as you mention later that you want.
