menu_post(3X)                                       menu_post(3X)

NAME
       menu_post  -  write or erase menus from associated subwin-
       dows

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  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).

       E_BAD_ARGUMENT
            Routine detected an incorrect or  out-of-range  argu-
            ment.

       E_POSTED
            The menu has already been posted.

       E_BAD_STATE
            Routine was called from an initialization or termina-
            tion 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.

       file <curses.h>.
