Ebook: Programming with curses

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.
