Member Function Documentation

◆ AlgorithmName()

static std::string Dwm::Dns::RRDataRRSIG::AlgorithmName ( uint8_t algo )

static

Returns the mnemonic for the given algorithm algo.

If algo is an algorithm we do not recognize, returns a string representation of algo.

◆ Decode()

const uint8_t* Dwm::Dns::RRDataRRSIG::Decode	(	const uint8_t *	pkt,
		const uint8_t *	ptr,
		uint16_t	pktlen,
		uint16_t	rdlen
	)

virtual

Decodes the RRSIG resource record data from buffer pkt of length pktlen, starting at ptr.

Returns the address immediately following the encoded RRSIG resource record data in pkt on success. Throws std::out_of_range if pkt was too short to contain an encoded RRSIG resource record data.

Implements Dwm::Dns::RRData.

◆ Encode()

uint8_t* Dwm::Dns::RRDataRRSIG::Encode	(	uint8_t *	pkt,
		uint8_t *	ptr,
		uint16_t	pktlen,
		LabelPositions &	lps
	)		const

virtual

Encodes the RRSIG resource record data into buffer @ pkt of length pktlen, starting at ptr.

Returns the address immediately following the encoded RRSIG resource record data in pkt on success. Throws std::out_of_range if pkt is too short to contain the encoded RRSIG resource record data.

Implements Dwm::Dns::RRData.
