</PRE>
<H2>NAME</H2><PRE>
       <STRONG>menu_post</STRONG>  -  write or erase menus from associated subwin-
       dows


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
       int post_menu(MENU *menu);
       int unpost_menu(MENU *menu);


</PRE>
<H2>DESCRIPTION</H2><PRE>
       The function <STRONG>post_menu</STRONG> displays a menu to  its  associated
       subwindow.   To trigger physical display of the subwindow,
       use  <STRONG>refresh</STRONG>  or  some  equivalent  <STRONG>curses</STRONG>  routine   (the
       implicit  <STRONG>doupdate</STRONG>  triggered  by  an <STRONG>curses</STRONG> input request
       will do). <STRONG>post_menu</STRONG> resets the  selection  status  of  all
       items.

       The  function  <STRONG>unpost_menu</STRONG> erases menu from its associated
       subwindow.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       These routines return one of the following:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno</STRONG>).

       <STRONG>E_BAD_ARGUMENT</STRONG>
            Routine detected an incorrect or  out-of-range  argu-
            ment.

       <STRONG>E_POSTED</STRONG>
            The menu has already been posted.

       <STRONG>E_BAD_STATE</STRONG>
            Routine was called from an initialization or termina-
            tion function.

       <STRONG>E_NO_ROOM</STRONG>
            Menu is too large for its window. You should consider
            to use <STRONG>set_menu_format()</STRONG> to solve the problem.

       <STRONG>E_NOT_POSTED</STRONG>
            The menu has not been posted.

       <STRONG>E_NOT_CONNECTED</STRONG>
            No items are connected to the menu.
