[LAD] Program execution in a program with good communications

Hello everyone! This is again a bit OT, but still. I have a program with two pthreads. One pthread is running an audio player on a file repeatedly, the other is waiting for a signal. If "the other" gets the signal or timeout, then it should tell the player to stop. Unfortunitely with mplayer kill -15 doesn't have the desired effect. So I thought: What if I could make mplayer's stdin available to the program and simply send character 'q'. But because of pthreads, I left fork and exec* alone and went with system. Any ideas what to do? If someone knows something nice with fork and the like, I've seen something with pipes for this. Otherwise the player-command I call can be called from within a shell script, so I can do funny things with redirections. I hope I made myself clear and didn't write too much again... :-( Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de
