Detailed Description

Encapsulates an NSEC bitmap. See section 4.1.2 of RFC4034.

Member Function Documentation

Decode()

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

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

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

Encode()

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

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

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