Member Function Documentation

Decode()

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

Decodes the label from buffer pkt of length pktlen, starting at ptr.

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

Encode()

uint8_t* Dwm::Dns::Label::Encode	(	uint8_t *	pkt,
		uint8_t *	ptr,
		uint16_t	pktlen
	)		const

Encodes the label into buffer @ pkt of length pktlen, starting at ptr.

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