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.
- This describes <STRONG>ncurses</STRONG> version 6.0 (patch 20170603).
+ This describes <STRONG>ncurses</STRONG> version 6.1 (patch 20180519).
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
The library uses the locale which the calling program has initialized.
That is normally done with <STRONG>setlocale</STRONG>:
- <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
+ <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
If the locale is not initialized, the library assumes that characters
are printable as in ISO-8859-1, to work with certain legacy programs.
screen oriented programs want this), the following sequence should be
used:
- <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
+ <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
Most programs would additionally use the sequence:
- <STRONG>nonl();</STRONG>
- <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
- <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
+ <STRONG>nonl();</STRONG>
+ <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
+ <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
Before a <STRONG>curses</STRONG> program is run, the tab stops of the terminal should be
set and its initialization strings, if defined, must be output. This
standard place. For example, if <STRONG>TERM</STRONG> is set to <STRONG>att4424</STRONG>, then the com-
piled terminal definition is found in
- <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
+ <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
(The <STRONG>a</STRONG> is copied from the first letter of <STRONG>att4424</STRONG> to avoid creation of
huge directories.) However, if <STRONG>TERMINFO</STRONG> is set to <STRONG>$HOME/myterms</STRONG>,
<STRONG>curses</STRONG> first checks
- <STRONG>$HOME/myterms/a/att4424</STRONG>,
+ <STRONG>$HOME/myterms/a/att4424</STRONG>,
and if that fails, it then checks
- <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
+ <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
This is useful for developing experimental definitions or when write
permission in <STRONG>/usr/share/terminfo</STRONG> is not available.
Tells <STRONG>ncurses</STRONG> where your home directory is. That is where it may read
and write auxiliary terminal descriptions:

other platforms:
- 1 = left
- 2 = right
- 3 = middle.
+ 1 = left
+ 2 = right

This variable lets you customize the mouse. The variable must be three
numeric digits 1-3 in any order, e.g., 123 or 321. If it is not speci-
<STRONG>o</STRONG> If <STRONG>ncurses</STRONG> is built to use hashed databases, then each entry in
this list may be the path of a hashed database file, e.g.,
- /usr/share/terminfo.db
+ /usr/share/terminfo.db
rather than
- /usr/share/terminfo/
+ /usr/share/terminfo/
The hashed database uses less disk-space and is a little faster
than the directory tree. However, some applications assume the
the remainder of that variable as a compiled terminal description.
You might produce the base64 format using <STRONG><A HREF="infocmp.1m.html">infocmp(1m)</A></STRONG>:
- TERMINFO="$(infocmp -0 -Q2 -q)"
- export TERMINFO
+ TERMINFO="$(infocmp -0 -Q2 -q)"
+ export TERMINFO
The compiled description is used if it corresponds to the terminal
identified by the <STRONG>TERM</STRONG> variable.
If the <STRONG>TERMPATH</STRONG> environment variable is not set, <STRONG>ncurses</STRONG> looks in the
files
- /etc/termcap, /usr/share/misc/termcap and $HOME/.termcap,
+ /etc/termcap, /usr/share/misc/termcap and $HOME/.termcap,
in that order.
the current user is the superuser (root), or if the application uses
setuid or setgid permissions:
- $TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.
+ $TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.

The standard include for <STRONG>ncurses</STRONG> is as noted in <STRONG>SYNOPSIS</STRONG>:
- <STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
+ <STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
This option is used to avoid filename conflicts when <STRONG>ncurses</STRONG> is
not the main implementation of curses of the computer. If <STRONG>ncurses</STRONG>
is installed disabling overwrite, it puts its headers in a subdi-
rectory, e.g.,
- <STRONG>#include</STRONG> <STRONG><ncurses/curses.h></STRONG>
+ <STRONG>#include</STRONG> <STRONG><ncurses/curses.h></STRONG>
