</PRE>
<H2>NAME</H2><PRE>
       <STRONG>menu_win</STRONG>  - make and break menu window and subwindow asso-
       ciations


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
       int set_menu_win(MENU *menu, WINDOW *win);
       WINDOW *menu_win(const MENU *menu);
       int set_menu_sub(MENU *menu, WINDOW *sub);
       WINDOW *menu_sub(const MENU *menu);
       int scale_menu(const MENU *menu, int *rows, int *columns);


</PRE>
<H2>DESCRIPTION</H2><PRE>
       Every  menu has an associated pair of <STRONG>curses</STRONG> windows.  The
       menu window displays any title and border associated  with
       the  window;  the menu subwindow displays the items of the
       menu that are currently available for selection.

       The first four functions get and set those windows.  It is
       not necessary to set either window; by default, the driver
       code uses <STRONG>stdscr</STRONG> for both.

       In the <STRONG>set_</STRONG> functions, window argument of <STRONG>NULL</STRONG> is  treated
       as  though  it  were  <STRONG>stsdcr</STRONG>.   A menu argument of <STRONG>NULL</STRONG> is
       treated as a request to change  the  system  default  menu
       window or subwindow.

       The  function <STRONG>scale_menu</STRONG> returns the minimum size required
       for the subwindow of <EM>menu</EM>.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       Routines that return pointers return <STRONG>NULL</STRONG> on error.   Rou-
       tines  that  return an integer return one of the following
       error codes:

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

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

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

       <STRONG>E_POSTED</STRONG>
            The menu has already been posted.

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

<H2>NOTES</H2><PRE>

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


</PRE>
<H2>PORTABILITY</H2><PRE>

       were not supported on Version 7 or BSD versions.
