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.
