Hi!

I would like to write a program in DOS that detects that an Escape key (or any other function key) has been pressed while writing a string to the screen, so the user could return back to the program menu without saving the data/pressing Enter.

How do I detect system-wide keystrokes like Ctrl+S before system does?

Would I have to write my own interrupt handler?

I've been looking over the net for these topics, so far I understand there are 3
ways:
1) using getch() (but not for system-wide keystrokes)
2) using keyboard buffer
3) using interrupt handler.

Correct me if I'm wrong. Or should these 3 ways be used together?
Please provide any useful links about this how it's done in C or even C++ as
they are easy portable to D.

Many thanks.

Kind regards,
Mitja

D programming doesn't support 16 bit programming, which would unfortunately include DOS. Sorry.

My mistake, I actually meant DOS shell for Windows XP.

No prob. Download the sources for microemacs from www.digitalmars.com. There's a Win32 version in there, that does direct I/O from the keyboard. I think it'll be helpful.
