That sounds amazingly familiar. :)  I'd like exactly the same thing.

Thanks for the reminder.  Check out the new libXamine module in XCB CVS.

Note, BTW, that the current state of libXamine is that it doesn't
currently track requests and replies.  However, most of the necessary
code to do so is already there; the main missing piece is the code to
associate replies with requests (much like XCB does), and map both to
the corresponding XamineDescription.

I also have a sample implementation of xev on top of libXamine; where
would be a good place to put that?  I didn't want to put it in xcb-util
or xcb-demos, since that stuff doesn't depend on Xamine.  As it's quite
small, I've attached it to this mail so you can look at it while we find
a place for it; it gives a good flavor to working with libXamine.  Note
that if you ignore printing code and window setup code, the actual code
that deals with Xamine is quite small.

Hope this helps.
