Detailed Description

Encapsulates A resource record data.

See RFC1035 for details.

Constructor & Destructor Documentation

◆ RRDataA()

Dwm::Dns::RRDataA::RRDataA ( const in_addr & inAddr )

Constructs an A record's data with the given IPv4 address inAddr.

Member Function Documentation

◆ Decode()

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

virtual

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

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

Implements Dwm::Dns::RRData.

◆ Encode()

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

virtual

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

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

Implements Dwm::Dns::RRData.
