Subject: Help: How to catch CTRL-C in applications compiled with djgpp
Cc: pem400 AT tcl DOT scl DOT crn DOT cn

Hi, 
    I need help for catching CTRL-C in my application compiled with
djgpp 1.08. Since go32 runs programs in protected mode, we can't
simply modify the DOS interrupt table for catching CTRL-C interrupt.
We have to deal with switching between DOS real mode and go32 protect
mode for transferring control to our interrupt service function
in protected mode when CTRL-C is caught by DOS. 

    Once I've changed go32 for such kind of mode switching. Although
it works and serves my purpose, I encounter problem of compiling each
new version of go32. And this is not too bad. It is the worst that
I have to distribute the modified go32 if I want to distribute my 
application. 

    I want to know if there are any other wiser method for catch
CTRL-C interrupt. Any suggestion will be greatly appreciated!

    Thanks in advance!
