menu_win - make and break menu window and subwindow associa-
tions
#include <menu.h>
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);
Every menu has an associated pair of curses 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 stdscr for both.
In the set_ functions, window argument of NULL is treated as
though it were stsdcr. A menu argument of NULL is treated
as a request to change the system default menu window or
subwindow.
The function scale_menu returns the minimum size required
for the subwindow of menu.
Routines that return pointers return NULL on error. Rou-
tines that return an integer return one of the following
error codes:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_POSTED
The menu has already been posted.
E_NOT_CONNECTED
No items are connected to the menu.

The header file <menu.h> automatically includes the header
file <curses.h>.

not supported on Version 7 or BSD versions.
