DESCRIPTION

16       ldns_rdf
17              Resource record data field.

19              The data is a network ordered array of bytes, which size is
20              specified by
21              the (16-bit) size field. To correctly parse it, use the type
22              specified in the (16-bit) type field with a value from \ref
23              ldns_rdf_type.
