- /* Like adns__findrr_checked, except that the datagram to compare
- * with can be specified explicitly.
- *
- * If the caller thinks they know what the owner of the RR ought to
- * be they can pass in details in eo_*: this is another (or perhaps
- * the same datagram), and a pointer to where the putative owner
- * starts in that datagram. In this case *eo_matched_r will be set
- * to 1 if the datagram matched or 0 if it did not. Either
- * both eo_dgram and eo_matched_r must both be non-null, or they
- * must both be null (in which case eo_dglen and eo_cbyte will be ignored).
- * The eo datagram and contained owner domain MUST be valid and
- * untruncated.
