NAME

       keyok - enable or disable a curses 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

       This  routine  is specific to ncurses.  It was not supported on Version 7, BSD or System V
       implementations.  It is recommended that any code depending on them be  conditioned  using
       NCURSES_VERSION.
