Thanks for your answer.
I never intentionally initiated communication from the daemon to the user app. The CFMessagePort was setup as a direct result of a specific request from the user app. This, at first sight at least, communication is always initiated by the client user app. However, I do admit that I need the daemon to notify the user app of interesting changes if the user app so requested, like hardware plug/unplug events, change in the hardware state, etc. I thought that a client request CFMessagePort would be the answer. Given my need of the daemon having to notify a "registered" user app of interesting events, how should I best proceed? If no user is logged on, then the user app will never request to be notified of interesting events. Each instance of the user app may request a new port to be setup, so I assume this should take of multiple users.
Would the CFNotificationCenter type suit my needs? Or am I going in the wrong direction entirely?
thanks,
Philip Lukidis
Would CFNotificationCenter work? Or CFSocket? I'll read up about these types.
thanks,
Philip Lukidis
