Hi Bruce, He's spawning child processes to handle the audio changes. These processes are separate processes from the PHP script being run by the webserver. However, they are children of the PHP script process since they have been started by the PHP script via popen() or proc_open(). His problem is that when the user changes page mid load, or shuts down the browser, the PHP script (the parent) is killed off by the webserver, but the child processes, sox and lame, continue to run. This ends up polluting CPU/memory with useless processes. What he wants is to have these processes also die. So by using proc_open() he can retrieve the output from the processes he has started and send that to the connected browser in chunks, but also detect if the browser has dropped its connection in which case he can manually kill of the child processes that aren't being killed automatically. HTH. Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
