NSTask and NSPipe are exactly what you need. Each instance of NSTask
can only be run once but you just make a new one for each user input.
When the task is complete you read the data out of the pipe and release
both objects. When the user makes a new request, repeat the process.

I'm working on a GUI wrapper for a program called Latin WORDS, which
was originally developed in Ada for DOS, but which has since been
ported to OS X. I've managed to create a working program using NSTask.
However, the program is designed to remain running and receive an
indefinite amount of input. As I understand, NSTask can only be run
once, which makes it not ideally suited to my needs, as I wind up
having to launch the program and quit it every time the user inputs a
new argument, which is quite inefficient. Does anybody know of a
better way to accomplish my goal? I've done a lot of searching, and I
think the system() C function looks promising, but it may also suffer
from the same issues as NSTask. Thanks in advance.
