This is a hole in the R3 specification.  There is no portable way to do this.
We are busily working on the R4 specification and it will include a public
function that will support a portable interface for retreiving the the name
of a widget.  

Until then the only way to get the name of a widget is to include IntrinsicP.h
and read the core.name field.  Here is some example source code.


char *
GetWidgetName(w)
Widget w;
{
# include <X11/IntrinsicP.h>
  
  return(w->core.name);
}
