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.
