While I was searching include files for Xt intrinsic prototype, I found a
routine called XtSetAsyncEventHandler().  I thought that this is it which was
suggested in the reply to my previous posting about event handling other than
event loop.  But, but I could not find any description in either Adrian Nye's
manual or DECwindows document set.  

I guess this intrinsic sets AST to display connection if using VMS, or other
async mechanism if using UNIX.  In fact, I have tried this intrinsic using
VAX/VMS V5.3 on VS3100, and it worked as I expected except passing
AST-parameter.     

Are there any datailed information or descriptions about this routine ?  Or,
are there any other Xt routines recommended to set AST mechanism  on VAX/VMS (
no event flag ;-) triggered by the availability of the X event ?  I want
to handle X events really asynchronously.

Thanks in advance..
