menu_items(3X)                                                  menu_items(3X)

NAME
       set_menu_items, menu_items, item_count - 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 argument.

       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(3)).

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).
