Given that you're using a scripting language, your best option is to leverage launchd's inetd compatibility. By doing so, you'll get automatic concurrency (at the cost of inefficiency) and implicit compatibility with other operating systems that supply [x]inetd. Assuming that your program is TCP based, then this should be sufficient: Once you make that change, you'll find the socket on stdin/stdout/ stderr at launch. This question has come up for me before and I suspect it will again. The example this time is the web "server" that serves the Ruby "rdoc" documentation. You start it with "gem server". It has a few options like which port which has a default. I have a launchd plist file that simply starts this up at boot. But, mostly so I can show off to my friends (if I had any :-), I'd like to start it up the first time I browse to that port. The man page for launchd.plist says that the process has to "check in" using the launch(3) API. "man 3 launch" gives me back nothing. So I am lost as to what API's there are. But, even if I could find them, thats really just half the problem. The real problem is I'm looking for a way to transfer the file descriptor from launchd to the gem server using a script. (I can't modify gem just to do this -- well, I suppose I could but that only defers the problem until next time this comes up). So, how is this done? Or... if I need to write some code, thats fine. But, where do I start? This email sent to zarzycki@apple.com This email sent to site_archiver@lists.apple.com
