  56 <H2>SYNOPSIS</H2><PRE>
  57        <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
  58        int set_menu_items(MENU *menu, ITEM **items);

  64 <H2>DESCRIPTION</H2><PRE>
  65        The function <STRONG>set_menu_items</STRONG> changes the item pointer array
  66        of  the  given  <EM>menu</EM>.   The  array must be terminated by a
  67        <STRONG>NULL</STRONG>.
  68
  69        The function <STRONG>menu_items</STRONG> returns  the  item  array  of  the
  70        given menu.
  71
  72        The  function  <STRONG>item_count</STRONG>  returns  the  count of items in
  73        <EM>menu</EM>.
  74
  75
  76 </PRE>
  77 <H2>RETURN VALUES</H2><PRE>
  78        The function <STRONG>menu_items</STRONG> returns a pointer  (which  may  be
  79        <STRONG>NULL</STRONG>).  It does not set errno.
  80
  81        The  function  <STRONG>item_count</STRONG>  returns <STRONG>ERR</STRONG> (the general <STRONG>curses</STRONG>
  82        error return value) if its <EM>menu</EM> parameter is <STRONG>NULL</STRONG>.
  83
  84        The function <STRONG>set_menu_items</STRONG> returns one of  the  following
  85        codes on error:
  86
  87        <STRONG>E_OK</STRONG> The routine succeeded.
  88
  89        <STRONG>E_BAD_ARGUMENT</STRONG>
  90             Routine  detected  an incorrect or out-of-range argu-
  91             ment.
  92
  93        <STRONG>E_NOT_CONNECTED</STRONG>
  94             No items are connected to the menu.
  95
  96        <STRONG>E_POSTED</STRONG>
  97             The menu is already posted.
  98
  99        <STRONG>E_SYSTEM_ERROR</STRONG>

 109 <H2>NOTES</H2><PRE>

 111        file <STRONG>&lt;curses.h&gt;</STRONG>.

 115 <H2>PORTABILITY</H2><PRE>
 116        These  routines  emulate  the System V menu library.  They
 117        were not supported on Version 7 or BSD versions.
 118
 119        The  SVr4  menu  library   documentation   specifies   the
 120        <STRONG>item_count</STRONG> error value as -1 (which is the value of <STRONG>ERR</STRONG>).
