Detailed Description

Encapsulates NSEC resource record data.

See RFC4034 for details.

◆ Decode()

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

virtual

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

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

Implements Dwm::Dns::RRData.

◆ Encode()

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

virtual

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

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

Implements Dwm::Dns::RRData.
