Detailed Description

Represents IGMPv1 (Internet Group Management Protocol ver 1) layer. This class represents all the different messages of IGMPv1

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 IGMPv1 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 IPv4Address::Zero if not provided

static bool pcpp::IgmpV1Layer::isDataValid	(	uint8_t const *	data,
		size_t	dataLen
	)

inlinestatic

A static method that validates the input data

Parameters

[in]	data	The pointer to the beginning of a byte stream of an IGMPv1 layer
[in]	dataLen	The length of the byte stream
