     menu_win - make and break menu window and subwindow associa-


     #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

     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.

          System error occurred (see errno).

          Routine detected an incorrect or out-of-range argument.

          The menu has already been posted.

          No items are connected to the menu.

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


     These routines emulate the System V menu library.  They were
     not supported on Version 7 or BSD versions.
