I don't think this is what was being asked; curses will allow you to preserve
your screen when *inside* an application, but I believe that the question
revolves around preserving the screen "as is" prior to the application
starting, and then restoring the screen when the application exits.  Unless
you have a bitmapped device which you could open and read, or your tty
driver uses streams, I don't think this could be done.
