Greetings.
Can a launchd job get any access to its invoking plist?
I'm writing a small application intended to be invoked, almost exclusively, from launchd. Its interface would be simpler if it could read the contents of the dictionary/plist which controls the job which launchd starts. It could potentially be invoked by more than one plist, and I'd like to preserve state keyed on (say) the job Label; it's invoked based on the WatchPaths element, and if it could see that key in the dictionary, then these paths wouldn't have to be duplicated in the ProgramArguments. I can work round the problem, but it feels like I'm missing a trick.
Is there any way to get access to this dictionary; or (since I know about SMJobCopyDictionary) is there any way to get access to the job's Label? The existence of SMJobCopyDictionary indicates that this information is available in principle.
I can't think of anything to google that gives me more than tutorials on using launchd.
I've tried asking on StackOverflow <http://stackoverflow.com/questions/20338636/>, but without success (the answer there is sensible, but somewhat tangential to the question).
Thanks for any pointers.
Best wishes,
Norman
