I have a widget ID and need to know what the name of that widget is.

	Users of R4 and later are best off using the XtName() function, which 
will work on both widgets and non-widget objects.

	If you are still using R3, you can use this simple bit of code to do 
what you want. Note that it depends on the widget's internal data structures 
and is not necessarily portable to future versions of Xt, including R4.

	#include <X11/CoreP.h>
	#include <X11/Xresource.h>
	String XtName (widget)
	Widget widget;	/* WILL work with non-widget objects */
	{
	return XrmNameToString(widget->core.xrm_name);
	}
