Detailed Description

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

Constructor & Destructor Documentation

◆ IgmpV2Layer() [1/2]

pcpp::IgmpV2Layer::IgmpV2Layer ( uint8_t *  data,
size_t  dataLen,
Layer prevLayer,
Packet packet 
)
inline

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

Parameters
[in]dataA pointer to the raw data
[in]dataLenSize of the data in bytes
[in]prevLayerA pointer to the previous layer
[in]packetA pointer to the Packet instance where layer will be stored in

◆ IgmpV2Layer() [2/2]

pcpp::IgmpV2Layer::IgmpV2Layer ( IgmpType  type,
const IPv4Address groupAddr = IPv4Address(),
uint8_t  maxResponseTime = 0 
)
inline

A constructor that allocates a new IGMPv2 header

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

◆ ~IgmpV2Layer()

pcpp::IgmpV2Layer::~IgmpV2Layer ( )
inline

A destructor for this layer (does nothing)

Member Function Documentation

◆ computeCalculateFields()

void pcpp::IgmpV2Layer::computeCalculateFields ( )
virtual

Calculate the IGMP checksum

Implements pcpp::Layer.
