Hi. A daemon process is running independently of my Cocoa app. Given a pid file of the daemon process in a known location, say /var/run/ somedaemon.pid, I would like my Cocoa app to read that file and check the process table to see if the daemon is actually running. If the daemon IS running, I want my
Cocoa app to change its Dock icon.
Is there a canonical Cocoa way of doing this?

You can adapt the techniques described in this tech note:
