       Every  form  has an associated pair of <STRONG>curses</STRONG> windows.  The form window
       displays any title and border associated  with  the  window;  the  form
       subwindow  displays  the items of the form that are currently available
       for selection.

       The first four  functions  get  and  set  those  windows.   It  is  not
       necessary to set either window; by default, the driver code uses <STRONG>stdscr</STRONG>
       for both.

       In the <STRONG>set_</STRONG> functions, window argument of <STRONG>NULL</STRONG> is treated as though  it
       were <STRONG>stsdcr</STRONG>.  A form argument of <STRONG>NULL</STRONG> is treated as a request to change
       the system default form window or subwindow.

       The function <STRONG>scale_form</STRONG> returns  the  minimum  size  required  for  the
       subwindow of <EM>form</EM>.


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       Routines  that  return  pointers  return  <STRONG>NULL</STRONG> on error.  Routines that
       return an integer return one of the following error codes:

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

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno(3)</STRONG>).

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

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

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