define_key(3)                                       define_key(3)


NAME
       define_key - define a keycode



SYNOPSIS
       #include <curses.h>

       int define_key(char *definition, int keycode);

DESCRIPTION
       This is an extension to the curses library.  It permits an
       application to define keycodes  with  their  corresponding
       control strings, so that the curses 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.

RETURN VALUE
       The keycode  must  be  greater  than  zero,  else  ERR  is
       returned.

PORTABILITY
       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 con-
       ditioned using NCURSES_VERSION.
