  67        Every  form  has an associated pair of <STRONG>curses</STRONG> windows.  The form window
  68        displays any title and border associated  with  the  window;  the  form
  69        subwindow  displays  the items of the form that are currently available
  70        for selection.
  71
  72        The first four  functions  get  and  set  those  windows.   It  is  not
  73        necessary to set either window; by default, the driver code uses <STRONG>stdscr</STRONG>
  74        for both.
  75
  76        In the <STRONG>set_</STRONG> functions, window argument of <STRONG>NULL</STRONG> is treated as though  it
  77        were <STRONG>stsdcr</STRONG>.  A form argument of <STRONG>NULL</STRONG> is treated as a request to change
  78        the system default form window or subwindow.
  79
  80        The function <STRONG>scale_form</STRONG> returns  the  minimum  size  required  for  the
  81        subwindow of <EM>form</EM>.
  82
  83
  84 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  85        Routines  that  return  pointers  return  <STRONG>NULL</STRONG> on error.  Routines that
  86        return an integer return one of the following error codes:
  87
  88        <STRONG>E_OK</STRONG> The routine succeeded.
  89
  90        <STRONG>E_SYSTEM_ERROR</STRONG>
  91             System error occurred (see <STRONG>errno(3)</STRONG>).
  92
  93        <STRONG>E_BAD_ARGUMENT</STRONG>
  94             Routine detected an incorrect or out-of-range argument.
  95
  96        <STRONG>E_POSTED</STRONG>
  97             The form has already been posted.
  98
  99        <STRONG>E_NOT_CONNECTED</STRONG>
 100             No items are connected to the form.
