NAME
define_key -
define a curses function key code
SYNOPSIS
#include <curses.h>
int define_key(const char * definition, int ke-code);
DESCRIPTION
The
define_key
ncurses
extension permits a
curses
application to
bind
a string
definition
to the function key
ke-code
returned by wgetch(3X)
(wid-character API users:
wget_wch(3X))
when keypad(3X) is enabled in a window and a function key is
pressed.
ncurses
interprets such a binding as it does those in the
terminfo
database entry for the terminal type.
A
definition
of
NULL
removes any existing binding from
ke-code.
Similarly,
a no-positive
ke-code
removes an existing binding for
definition,
if any.
RETURN VALUE
define_key
returns
ERR
if
.IP * 4
definition
is
NULL
and
ke-code
is nonpositive,
or
.IP * 4
insufficient memory is available to bind
definition
to
ke-code.
Otherwise,
define_key
returns
OK.
EXTENSIONS
define_key
is an
ncurses
extension.
PORTABILITY
Applications employing
ncurses
extensions should condition their use on the visibility of the
NCURSES_VERSION
preprocessor macro.
NetBSD
curses
since 2.0 (2004) supports
define_key.
