    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.  

    SEE ALSO

    define_key(3X).
