Detailed Description

Represents IGMPv2 (Internet Group Management Protocol ver 2) layer. This class represents all the different messages of IGMPv2

Constructor & Destructor Documentation

inline

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

Parameters

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

inlineexplicit

A constructor that allocates a new IGMPv2 header

Parameters

[in]	type	The message type to set
[in]	groupAddr	The multicast address to set. This is an optional parameter and has a default value of unspecified/zero IPv4 address
[in]	maxResponseTime	The max response time to set. This is an optional parameter and has a default value of 0 if not provided
