However I used signals rather than holding open stdin. It's a little ugly but very simple, From memory: STOP pauses CONT resumes QUIT causes it to stop playing and terminates the process To play a new song, start a new process. USR1 does something, I think USR2 does something too. I just can't remember what. There should be documentation for mpg123 that explains all the signals and how it reacts. If not you could find it fairly easily by browsing the source. David -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
