 *              removed in the future.  Applications should switch to the

 NAME
    H5Rget_obj_type1
 PURPOSE
    Retrieves the type of object that an object reference points to
 USAGE
    H5G_obj_t H5Rget_obj_type1(id, ref_type, ref)
        hid_t id;       IN: Dataset reference object is in or location ID of

        H5R_type_t ref_type;    IN: Type of reference to query
        void *ref;          IN: Reference to query.

 RETURNS
    Success:	An object type defined in H5Gpublic.h
    Failure:	H5G_UNKNOWN
 DESCRIPTION
    Given a reference to some object, this function returns the type of object
    pointed to.
