How could this be accomplished? Is it even possible?
You'd have to do this in the parent. You can duplicate the file
descriptor, so that writing to either goes to the same spot, but you
can't "fork" the file descriptor, so that writing to one goes to 2 spots.
Hm.. you could potentially do this via an intermediary process that does
the copying. Then you could avoid writing the buffering code in your
parent or child.
i.e. something like the Unix tee command.
