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.

SEE ALSO

       define_key(3NCURSES).
