NAME
	GT_GetGadgetAttrsA -- request the attributes of a GadTools gadget. (V39)
	GT_GetGadgetAttrs -- varargs stub for GT_GetGadgetAttrsA(). (V39)

   SYNOPSIS
	numProcessed = GT_GetGadgetAttrsA(gad, win, req, taglist)
	                                  A0   A1   A2   A3

	LONG GT_GetGadgetAttrsA(struct Gadget *, struct Window *,
	                        struct Requester *, struct TagItem *);

	numProcessed = GT_GetGadgetAttrs(gad, win, req, firsttag, ...)

	LONG GT_GetGadgetAttrs(struct Gadget *, struct Window *,
                              struct Requester *, Tag, ...);

   FUNCTION
	Retrieve the attributes of the specified gadget, according to the
	attributes chosen in the tag list.  For each entry in the tag list,
	ti_Tag identifies the attribute, and ti_Data is a pointer to
	the long variable where you wish the result to be stored.

   INPUTS
	gad - pointer to the gadget in question. May be NULL, in which case
	      this function returns 0
	win - pointer to the window containing the gadget.
	req - reserved for future use, should always be NULL
	taglist - pointer to TagItem list.

   EXAMPLE
		long top = 0;
		long selected = 0;
		long result;
		result = GT_GetGadgetAttrs( listview_gad, win, NULL,
			GTLV_Top, &top,
			GTLV_Selected, &selected,
			TAG_DONE );
		if ( result != 2 )
		{
			printf( "Something's wrong!" );
		}

   WARNING
	The pointers you provide within the tag list to store the return
	values MUST POINT TO LONGWORDS. That is, even if the type of a
	return value is defined as (UWORD *), you must pass a pointer to
	a longword of memory.
