Detailed Description

Base class for ICMPv6 protocol layers which provides common logic for ICMPv6 messages.

Constructor & Destructor Documentation

IcmpV6Layer() [1/2]

pcpp::IcmpV6Layer::IcmpV6Layer ( uint8_t *  data, size_t  dataLen, Layer *  prevLayer, Packet *  packet  )

inline

A constructor that creates the layer from an existing packet raw data

Parameters

data	A pointer to the raw data
dataLen	Size of the data in bytes
prevLayer	A pointer to the previous layer
packet	A pointer to the Packet instance where layer will be stored in

IcmpV6Layer() [2/2]

pcpp::IcmpV6Layer::IcmpV6Layer	(	ICMPv6MessageType	msgType,
		uint8_t	code,
		const uint8_t *	data,
		size_t	dataLen
	)

A constructor that allocates a new ICMPv6 layer with type, code and data

Parameters

[in]	msgType	Message type of the ICMPv6 layer
[in]	code	Code field of the ICMPv6 layer
[in]	data	A pointer to the payload to set
[in]	dataLen	The length of the payload
