method of updating character screens with reasonable optimization.
This implementation is "new curses" (ncurses) and is the approved
replacement for 4.4BSD classic curses, which has been discontinued.

The <STRONG>ncurses</STRONG> library emulates the curses library of System V Release 4
UNIX, and XPG4 (X/Open Portability Guide) curses (also known as XSI
curses). XSI stands for X/Open System Interfaces Extension. The
<STRONG>ncurses</STRONG> library is freely redistributable in source form. Differences

- <STRONG>PORTABILITY</STRONG> sections below and described in detail in the respective
- <STRONG>EXTENSIONS</STRONG>, <STRONG>PORTABILITY</STRONG> and <STRONG>BUGS</STRONG> sections of individual man pages.

features which cannot be implemented by a simple add-on library but
option, or (if it has been generated) with the debugging library
<STRONG>-lncurses_g</STRONG>. (Your system integrator may also have installed these
