keyok(3x) Library calls keyok(3x)
keyok - enable or disable a curses function key code
#include <curses.h>
int keyok(int key-code, bool bf);
The keyok ncurses extension permits a curses application to disable a
function key key-code returned by wgetch(3x) (wide-character API users:
wget_wch(3x)). Key codes that have been disabled can be re-enabled.
bf selects the desired enablement status. This operation is more fine-
grained than calling keypad(3x), which affects all function keys.
keyok returns ERR if
o key-code is nonpositive,
o key-code is not a recognized value, or
o enablement of key-code is already in the desired state.
Otherwise, keyok returns OK.
keyok is an ncurses extension.
Applications employing ncurses extensions should condition their use on
the visibility of the NCURSES_VERSION preprocessor macro.
NetBSD curses since 2.0 (2004) supports keyok.
