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. Rou-
tines 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</STRONG>).
<STRONG>E_BAD_ARGUMENT</STRONG>
Routine detected an incorrect or out-of-range argu-
ment.
<STRONG>E_POSTED</STRONG>
The form has already been posted.
<STRONG>E_NOT_CONNECTED</STRONG>
No items are connected to the form.
