Описание (Description)
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.
