a pointer to an XFontStruct (documented as just "XFontStruct" not
"XFontStruct *" in the Xaw manual).

This can be found in R3 using the following ..

	XFontStruct *afont;

	afont = XLoadQueryFont(XtDisplay(label_widget),
		"-adobe-helvetica-hold-o-normal--24-240-75-75-p-138-iso8859-1");
	if (afont != NULL) {
		i = 0;
		XtSetArg(args[i], XtNfont, afont); i++;
		XtSetValues(label_widget, args, i);
	}

or even better in R4 ...

	String font_name =
	     "-adobe-helvetica-hold-o-normal--24-240-75-75-p-138-iso8859-1";

	XtVaSetValues(label_widget, XtVaTypedArg, XtNfont, XtRString,
			font_name, strlen(font_name), NULL);

using the R4 varargs interface in Xt which calls the StringToFontStruct
converter.
