In the meantime, there are some less-than-ideal workarounds:

o As Shaun mentioned, there's KUNC.

o Another option is for your launchd property list to specify some on-demand criteria that your KEXT satisfies. For example, your launchd property list could register a UNIX domain socket with a well known path. When your KEXT comes up, it connects to that socket, thereby triggering the launch of your daemon.

That's good information for the list. In my case, I have a daemon that is always up for other reasons. It just needs to know when my kext is loaded. I looked at IOServiceAddMatchingNotification(). That seems pretty straight-forward. What I'm not clear on is what stage my driver will be in when I get a notice in my callback. What I want my daemon to do is to configure my kext, then listen for messages from it that it must respond to. I expect at the time my daemon is launched there may be driver instances already published before my daemon came up. The kext will be using default behaviors at this point, because it can't read any settings from disk itself. The daemon will configure the kext to handle future events, then start listening to the it for messages. That's as much as I can do for existing instances. In the case of notices I receive in my callback... So long as there is any published driver I want to listen for messages from my kext. I can track that by counting publications vs. terminations. If I receive a first published notice for my driver at a time when there are no other published services, my daemon need to configure the kext via is user client and start listening for messages from it. In this case, however, I don't want my driver's validateNewMedia() method to execute before I have sent configuration info to the kext's user client and I am listening for messages. Is there a way I can count on doing this in terms of the order of operations? I mean, if I set this all up when I receive the publish notice in the daemon, before exiting the callback, am I ok? Is there something else I should do? I'm just trying to figure out how to make this work. Thanks, Eric _______________________________________________ Do not post admin requests to the list.
