keyok(3x)                        Library calls                       keyok(3x)
       keyok - enable or disable a curses keycode
       #include <curses.h>
       int keyok(int keycode, bool enable);
       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.
       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.
       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.
