NAME

       menu_items  - make and break connections between items and
       menus


SYNOPSIS

       #include <menu.h>
       int set_menu_items(MENU *menu, ITEM **items);
       ITEM **menu_items(const MENU *menu);
       int item_count(const MENU *menu);


DESCRIPTION

       The function set_menu_items changes the item pointer array
       of  the  given  menu.   The  array must be terminated by a
       NULL.

       The function menu_items returns  the  item  array  of  the
       given menu.

       The  function  item_count  returns  the  count of items in
       menu.


RETURN VALUE

       The function menu_items returns a pointer  (which  may  be
       NULL).  It does not set errno.

       The  function  item_count  returns ERR (the general curses
       error return value) if its menu parameter is NULL.

       The function set_menu_items returns one of  the  following
       codes on error:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine  detected  an incorrect or out-of-range argu-
            ment.

       E_NOT_CONNECTED
            No items are connected to the menu.

       E_POSTED
            The menu is already posted.

       E_SYSTEM_ERROR
            System error occurred (see errno).


SEE ALSO

       curses(3x), menu(3x).


NOTES

       The header file <menu.h> automatically includes the header
       file <curses.h>.


PORTABILITY

       These  routines  emulate  the System V menu library.  They
       were not supported on Version 7 or BSD versions.

       The  SVr4  menu  library   documentation   specifies   the
       item_count error value as -1 (which is the value of ERR).
