keyok(3ncurses)


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).
