NAME
       keyok - enable or disable a keycode

SYNOPSIS
       #include <curses.h>

       int keyok(int keycode, bool enable);

DESCRIPTION
       This is an extension to the curses library.  It permits an application to disable specific keycodes, rather than use the keypad function to
       disable all keycodes.  Keys that have been disabled can be re-enabled.

RETURN VALUE
       The keycode must be greater than zero, else ERR is returned.  If it does not correspond to a defined key, then ERR  is  returned.   If  the
       enable parameter is true, then the key must have been disabled, and vice versa.	Otherwise, the function returns OK.

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 conditioned using NCURSES_VERSION.
