Hello.  I'm developing my first Motif application, and I have a question
about XmString things.  This is the situation:  I need to obtain the
labelString resource from a pushbutton and use it to set the string
resource of another widget:

	Widget		w1, w2;
	XmString	str;
        Arg		arg;

	XtSetArg(arg, XmNlabelString, &str);
	XtGetValues(w1, &arg, 1);
	XtSetArg(arg, XmNmessageString /* or whatever */, str);
	XtSetValues(w2, &arg, 1);

This seems to work.  My question: does 'str' have to be deallocated at this
point?  That is, did XtGetValues() create an entire new instance of the
XmString?  Does XtSetValues() create an internal instance of the XmString,
or does it just set up pointers to 'str'?  Please help if you can.
