Hello, I have a large experience in developing cocoa applications, but none with launchd daemons. I would like to develop a system daemon running from start to shutdown and I know, from the documentation below [1] that there are a few requirements. I have tried to compile the sampleD daemon, but it is way outdated and I can't make it work… despite setting it to 64bits and mountain lion. So I have a few questions: 1. Which language can I use for my daemon? Obj-C? C? C++? 2. Is there a specific template to use? I saw an XPC service template in Xcode but that's all. 3. I know I need to handle SIGTERM, but I don't know how. Are there any other requirements? 4. I think that once launched, the daemon must have an infinite loop, right? ShouldI put a sleep() call inside? If yes, for how long? These are pretty basic questions. I will gladly take any help, any sample code or any link towards documentations… in short amything is good to help me start.
