[LAD] Program execution in a program with good communications

[Julien Claassen]

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
