MENU_POST(3)            NetBSD Library Functions Manual           MENU_POST(3)


NAME

     post_menu unpost_menu -- post (draw) or unpost a menu


LIBRARY

     Curses Menu Library (libmenu, -lmenu)


SYNOPSIS

     #include <menu.h>

     int
     post_menu(MENU *menu);

     int
     unpost_menu(MENU *menu);


DESCRIPTION

     The post_menu() function causes the menu to be drawn on the screen.  Any
     functions defined by either set_menu_init() or set_item_init() (see
     menu_hook(3)) are called before the menu is placed on the screen.  The
     unpost_menu() does the opposite, it removes a menu from the screen.  Any
     functions defined by both set_menu_term() and set_item_term() (see
     menu_hook(3)) are called prior to the menu's removal.


RETURN VALUES

     The functions return one of the following error values:

     E_OK             The function was successful.
     E_SYSTEM_ERROR   There was a system error during the call.
     E_BAD_ARGUMENT   One or more of the arguments passed to the function was
                      incorrect.
     E_POSTED         The menu is already posted.
     E_BAD_STATE      The function was called from within an initialization or
                      termination routine.
     E_NO_ROOM        The menu does not fit within the subwindow.
     E_NOT_CONNECTED  The item is not connected to a menu.
