Given the ability to call c routines from icon, and for c routines
to call icon, has anyone done an Xwindows interface for icon? If not,
I volunteer (ugh). In order to do this, I need the following
information.

I looked for Griswald's book on implementation of icon, and no one
has it. Anywhere. What I need is a better discription than what the
tech reference that came with rev 8 has (which refers to Griswald's
book). I have written interpretive interfaces before, and I have
a rough idea how it may work, but I would appreciate someone sending
me any information on icon calling conventions and function
return conventions. Or at least where to look. 

Handling callbacks from X would be done through C interfaces to ICON.
The callbacks would be registered through the runtime and would
return through the runtime. My confusion is about how the status
information, or pointers to X structures would be passed back to ICON. 

Anyone willing to help, kindly let me know through email.
