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  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.

RETURN VALUE

       These routines return one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno).

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

       E_POSTED
            The menu has already been posted.

       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.

       E_NOT_POSTED
            The menu has not been posted.

       E_NOT_CONNECTED
            No items are connected to the menu.

       ported on Version 7 or BSD versions.
