Hi.  I would like to use the callback function for interrupt 33, which
allows you to install a routine that is called whenever an
"asyncronous" event occurs (via the mouse driver).  However, how can I
do this from a DPMI program?  Since the system will be in real mode at
the time of the interrupt, it cannot call my protected mode routine.
I know I could just poll int 33 directly from my program (using
standard real to dpmi reflection), but this seems like a waste, given
most of the time it won't be returning anything useful...

Regards,

Bruce.
