key_defined(3) UNIX Programmer's Manual key_defined(3)
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 sup-
ported on Version 7, BSD or System V implementations. It is
recommended that any code depending on them be conditioned
using NCURSES_VERSION.
