- <STRONG>#include</STRONG> <STRONG><menu.h></STRONG>
- int set_menu_win(MENU *menu, WINDOW *win);
- WINDOW *menu_win(const MENU *menu);

-<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>.
-

-<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.
