ldns_rdf Resource record data field. The data is a network ordered array of bytes, which size is specified by the (16-bit) size field. To correctly parse it, use the type specified in the (16-bit) type field with a value from \ref ldns_rdf_type. struct ldns_struct_rdf { The size of the data (in octets): size_t _size; The type of the data: ldns_rdf_type _type; Pointer to the data (raw octets): void *_data; }; typedef struct ldns_struct_rdf ldns_rdf;
