<H2>DESCRIPTION</H2><PRE>
The <STRONG>ncurses</STRONG> library routines give the user a terminal-
independent method of updating character screens with rea-
- sonable optimization. This implementation is ``new
- curses'' (ncurses) and is the approved replacement for
- 4.4BSD classic curses, which has been discontinued. This
- describes <STRONG>ncurses</STRONG> version 5.9 (patch 20130309).
+ sonable optimization. This implementation is "new curses"
+ (ncurses) and is the approved replacement for 4.4BSD clas-
+ sic curses, which has been discontinued. This describes
+ <STRONG>ncurses</STRONG> version 5.9 (patch 20140809).
The <STRONG>ncurses</STRONG> library emulates the curses library of System
V Release 4 UNIX, and XPG4 (X/Open Portability Guide)
ing the runtime behavior of the <STRONG>ncurses</STRONG> library. The most
important ones have been already discussed in detail.
- BAUDRATE
- The debugging library checks this environment vari-
- able when the application has redirected output to a
- file. The variable's numeric value is used for the
- baudrate. If no value is found, <STRONG>ncurses</STRONG> uses 9600.
- This allows testers to construct repeatable test-
- cases that take into account costs that depend on
- baudrate.
-
CC When set, change occurrences of the command_character
(i.e., the <STRONG>cmdch</STRONG> capability) of the loaded terminfo
entries to the value of this variable. Very few ter-
ignores it if it does not happen to be a single char-
acter.

COLUMNS
Specify the width of the screen in characters.
Applications running in a windowing environment usu-
tive value from zero to the terminfo <STRONG>max_colors</STRONG> value
is allowed.
+ NCURSES_CONSOLE2
+ This applies only to the MinGW port of ncurses.
+
+ The <STRONG>Console2</STRONG> program's handling of the Microsoft Con-
+ sole API call <STRONG>CreateConsoleScreenBuffer</STRONG> is defective.
+ Applications which use this will hang. However, it
+ is possible to simulate the action of this call by
+ mapping coordinates, explicitly saving and restoring
+ the original screen contents. Setting the environ-
+ ment variable <STRONG>NCGDB</STRONG> has the same effect.

NCURSES_GPM_TERMS
This applies only to ncurses configured to use the
GPM interface.
variable to disable the feature. You can also adjust
your <STRONG>stty</STRONG> settings to avoid the problem.
- NCURSES_NO_MAGIC_COOKIES
+ NCURSES_NO_MAGIC_COOKIE
Some terminals use a magic-cookie feature which
requires special handling to make highlighting and
other video attributes display properly. You can
TERM Denotes your terminal type. Each terminal type is
distinct, though many are similar.
+ <STRONG>TERM</STRONG> is commonly set by terminal emulators to help
+ applications find a workable terminal description.
+ Some of those choose a popular approximation, e.g.,
+ "ansi", "vt100", "xterm" rather than an exact fit.
+ Not infrequently, your application will have problems
+ with that approach, e.g., incorrect function-key def-
+ initions.
+
+ If you set <STRONG>TERM</STRONG> in your environment, it has no effect
+ on the operation of the terminal emulator. It only
+ affects the way applications work within the termi-
+ nal. Likewise, as a general rule (<STRONG>xterm</STRONG> being a rare
+ exception), terminal emulators which allow you to
+ specify <STRONG>TERM</STRONG> as a parameter or configuration value do
+ not change their behavior to match that setting.
+
TERMCAP
If the <STRONG>ncurses</STRONG> library has been configured with <EM>term-</EM>
<EM>cap</EM> support, <STRONG>ncurses</STRONG> will check for a terminal's
applications to be built using either library from
the same set of headers.
+ --with-pthread
+ The configure script renames the library. All of the
+ library names have a "t" appended to them (before any
+ "w" added by <STRONG>--enable-widec</STRONG>).
+
+ The global variables such as <STRONG>LINES</STRONG> are replaced by
+ macros to allow read-only access. At the same time,
+ setter-functions are provided to set these values.
+ Some applications (very few) may require changes to
+ work with this convention.
