Re: Process ID of Xserver

well, 'ps auxwwj' will list all processes along with their parent pids. the X server should be called 'X11', with the full path:

/Applications/Utilities/X11.app/Contents/MacOS/X11

oddly enough, on my system there were two of them, one was the parent of the other.

I think this qualifies as an unreliable way. What if someone is using XDarwin? What if they have more than one instance of X11 running on separate screens? ...

Is there a reliable way to get the PID of the Xserver which owns the root window? Either a shell method or one which runs within a child process would be OK. I know I can get the parent's PID in a program, but I don't think I can be sure that that will always be the server. For example the parent might be an XTerm.

With the PID, I can get the server app's serial number which I can then use to talk to some of the event manager routines.

The AppleWM extension sets some properties on the root window, but this is not one of them. What are you planning to do with the Event Manager routines? This is perhaps an area where a new feature would be useful.
