key_defined(3X) key_defined(3X)
key_defined - check if a keycode is defined
#include <curses.h>
int key_defined(const char *definition);
This is an extension to the curses library. It permits an
application to determine if a string is currently bound to any
keycode.
If the string is bound to a keycode, its value (greater than zero) is
returned. If no keycode is bound, zero is returned. If the string
conflicts with longer strings which are bound to keys, -1 is
returned.
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.
