menu_post(3x)                    Library calls                   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.

PORTABILITY

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