       #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  equiva-
       lent 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.

       E_BAD_STATE
	    Routine was called from an initialization or termination function.

       E_NO_ROOM
	    Menu  is  too  large  for  its  window. You should consider to use
	    set_menu_format() to solve the problem.
