key_defined(3NCURSES)                                                       key_defined(3NCURSES)



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 Sys-
       tem  V  implementations.  It is recommended that any code depending on them be conditioned
       using NCURSES_VERSION.

SEE ALSO
       define_key(3NCURSES).
