define_key(3X) define_key(3X)
define_key - define a keycode
#include <curses.h>
int define_key(const char *definition, int keycode);
This is an extension to the curses library. It permits an
application to define keycodes with their corresponding control
strings, so that the ncurses library will interpret them just as
it would the predefined codes in the terminfo database.
If the given string is null, any existing definition for the
keycode is removed. Similarly, if the given keycode is negative
or zero, any existing string for the given definition is removed.
The keycode must be greater than zero, and the string non-null,
otherwise ERR is returned. ERR may also be returned if there is
insufficient memory to allocate the data to store the definition.
If no error is detected, OK is returned.
These routines are specific to ncurses. They were not supported
on Version 7, BSD or System V implementations. It is recommended
that any code depending on them be conditioned using
NCURSES_VERSION.
