When you say "send 'q' character", do you mean a 'q' keystroke (like a
curses app), or text fed to its stdin? If the former, I don't think
NSTask will do the trick. I'm sure others can give advice on how to
handle terminal-manipulation from Cocoa, but I wouldn't expect
anything easy..

See -[NSTask terminate].

Reading from the pipe connected to your C app's stdout will provide
you with its output. Again, see the NSTask docs for details:
