NAME
key_defined - check if a keycode is defined
SYNOPSIS
#include <curses.h>
int key_defined(const char *definition);
DESCRIPTION
This is an extension to the curses library.
It permits an application to determine if a string is currently bound
to any keycode.
RETURN VALUE
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.
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.
