Resource record types.

inline |
Sets and returns the RRDATA of the resource record.
Note that this should normally only be called with one or two arguments, which means we're using a known RRDATA encoding. If you specify the third argument (resource record type), it MUST be a type that we don't handle and rrdata must be RRDataUnknown (which is just a blob stored in a strong).
| const uint8_t* Dwm::Dns::ResourceRecord::Decode | ( | const uint8_t * | pkt, |
| const uint8_t * | ptr, | ||
| uint16_t | pktlen | ||
| ) |
Decodes the resource record from buffer pkt of length pktlen, starting at ptr.
Returns the address immediately following the encoded DHCID resource record data in pkt on success. Throws std::out_of_range if pkt was too short to contain an encoded resource record.

| ) | const |
Encodes the resource record into buffer @ pkt of length pktlen, starting at ptr.
Returns the address immediately following the encoded resource record in pkt on success. Throws std::out_of_range if pkt is too short to contain the encoded resource record.
