NAME
       menu_post - write or erase menus from associated subwindows

SYNOPSIS
       #include <menu.h>
       int post_menu(MENU *menu);
       int unpost_menu(MENU *menu);

DESCRIPTION
       The  function  post_menu displays a menu to its associated subwindow.  To trigger physical display of
       the subwindow, use refresh or some equivalent curses routine (the implicit doupdate triggered  by  an
       curses input request will do). post_menu resets the selection status of all items.

       The function unpost_menu erases menu from its associated subwindow.
