curses is a UNIX library of functions for controlling a terminal's display screen from a C program. It can be used to provide a screen driver for a program (such as a visual editor) or to improve a program's user interface. This handbook will help you make use of the curses library in your C programs. We have presented ample material on curses and its implementation in UNIX so that you understand the whole, as well as its parts. Note: This handbook covers Ken Arnold's original Berkeley implementation of curses, not the System V version. Topics covered include: - Windows, screens, and images. - Multiple windows. - The WINDOW structure.
