Instead, 2N/A * curses, by knowing what's on the screen can optimally 2N/A * update it with the information of the new program. 2N/A * 1: Tell <curses> that the stored image should be 2N/A * the physical image. Sort of like a huge waddstr onto 2N/A * curscr. This can be used when a library wants to save 2N/A * a screen image and restore it at a later time. 2N/A * 2: Tell <curses> that the stored image is the physical 2N/A * image and also it is what the new program wants on the 2N/A * screen.
