NAME

       post - 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 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 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 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.
