<H2>NAME</H2><PRE>
       <B>menu_items</B>  - make and break connections between items and
       menus


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <B>#include</B> <B>&lt;menu.h&gt;</B>
       int set_menu_items(MENU *menu, ITEM **items);
       ITEM **menu_items(const MENU *menu);
       int item_count(const MENU *menu);


</PRE>
<H2>DESCRIPTION</H2><PRE>
       The function <B>set_menu_items</B> changes the item pointer array
       of  the  given  <I>menu</I>.   The  array must be terminated by a
       <B>NULL</B>.

       The function <B>menu_items</B> returns  the  item  array  of  the
       given menu.

       The  function  <B>item_count</B>  returns  the  count of items in
       <I>menu</I>.


</PRE>
<H2>RETURN VALUES</H2><PRE>
       The function <B>menu_items</B> returns <B>NULL</B> on error.

       The function <B>item_count</B> returns <B>ERR</B>  (the  general  <B>curses</B>
       error return value) on error.

       The  function  <B>set_menu_items</B> returns one of the following
       codes on error:

       <B>E_OK</B> The routine succeeded.

       <B>E_SYSTEM_ERROR</B>
            System error occurred (see <B>errno</B>).

       <B>E_BAD_ARGUMENT</B>
            Routine detected an incorrect or  out-of-range  argu-
            ment.

       <B>E_POSTED</B>
            The menu is already posted.

       <B>E_NOT_CONNECTED</B>
            No items are connected to the menu.

<H2>NOTES</H2><PRE>
       The header file <B>&lt;menu.h&gt;</B> automatically includes the header
       file <B>&lt;curses.h&gt;</B>.


</PRE>
<H2>PORTABILITY</H2><PRE>
       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
       <B>item_count</B> error value as -1 (which is the value of  <B>ERR</B>).
