 * Function:	H5Pget_filter_by_id2
 *
 * Purpose:	This is an additional query counterpart of H5Pset_filter() and
 *              returns information about a particular filter in a permanent
 *		or transient pipeline depending on whether PLIST_ID is a
 *		dataset creation or transfer property list.  On input,
 *		CD_NELMTS indicates the number of entries in the CD_VALUES
 *		array allocated by the caller while on exit it contains the
 *		number of values defined by the filter.  FILTER_CONFIG is a bit
 *      field contaning encode/decode flags from H5Zpublic.h.  The ID
 *      should be the filter ID to retrieve the parameters for.  If the
 *      filter is not set for the property list, an error will be returned.
 *
 * Return:	Success:	Non-negative
 *		Failure:	Negative
