menu_post(3X)							 menu_post(3X)

NAME
       menu_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  equiva-
       lent 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.

SEE ALSO
       curses(3X), menu(3X).

NOTES
       The  header  file  <menu.h>  automatically  includes  the  header  file
       <curses.h>.

PORTABILITY
       These routines emulate the System V menu	library.  They were  not  sup-
       ported on Version 7 or BSD versions.
