Usefull Refcon

[blakem@world.std.com (Blake Meike)]

I'd like to be able to find the lisp object that belongs to some
of the Mac 'objects' I have floating around my program.  A standard
technique is to put the 'name' of the lisp object into the refcon
of the Mac 'object'.  But how do I convince lisp that the value that
I get out of the refcon is really an object.
 
In short, I want to do:
 
  (ask
    (some-kind-of-coersion
      (rref my-control control.rfCon))
    (....))
 
Any suggestions?
 
Thank you,
Blake Meike
