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

   ncurses(3NCURSES), menu(3MENU).

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).
