NAME

       post_menu, unpost_menu - 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(3X) 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.

RETURN VALUE

       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.
