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	 equiva-
     lent curses routine (the implicit doupdate triggered by an curses input re-
     quest will do).  post_menu resets the selection status of all items.

     The function unpost_menu erases menu from its associated subwindow.

     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

     on Version 7 or BSD versions.
