menu_post(3X)                                              menu_post(3X)

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.

       <curses.h>.

       supported on Version 7 or BSD versions.
