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).


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 sup-
       ported 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).
