post_menu, unpost_menu - write or erase menus from associated subwindows

       Juergen Pfeifer.  Manual pages and adaptation for new curses by Eric S. Raymond.

       The  function  post_menu displays a menu to its associated subwindow.  To trigger physical display of the
       subwindow, use refresh(3NCURSES) 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.

       These routines emulate the System V menu library.  They were not supported on Version 7 or BSD versions.

       These routines return one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno(3)).

       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 using 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.
