how to detect a keyboard event in C without prompting the user in linux? That is the program running should terminate by pressing any key. can anyone please help with this?<

Answer 1

If you want to do that in a graphical application, you should use some libraries to do this.

Such a simple task can be easily done with whatever library (even low level ones like Xlib).

Just choose one and look for a tutorial that shows how to handle keyboard events.
