7

SYNOPSIS

9       #include <menu.h>
10       int post_menu(MENU *menu);

12

DESCRIPTION

14       The function post_menu displays a menu to its associated subwindow.  To
15       trigger physical display of the subwindow, use refresh or some  equiva‐
16       lent curses routine (the implicit doupdate triggered by an curses input
17       request will do). post_menu resets the selection status of all items.
18
19       The function unpost_menu erases menu from its associated subwindow.
