Detailed Description

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

Constructor & Destructor Documentation

◆ IgmpV1Layer() [1/2]

pcpp::IgmpV1Layer::IgmpV1Layer ( uint8_t *  data,
size_t  dataLen,
Layer prevLayer,
Packet packet 

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

[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

◆ IgmpV1Layer() [2/2]

pcpp::IgmpV1Layer::IgmpV1Layer ( IgmpType  type,
const IPv4Address groupAddr = IPv4Address() 

A constructor that allocates a new IGMPv1 header

[in]typeThe message type to set
[in]groupAddrThe multicast address to set. This is an optional parameter and has a default value of IPv4Address::Zero if not provided

◆ ~IgmpV1Layer()

pcpp::IgmpV1Layer::~IgmpV1Layer ( )

A destructor for this layer (does nothing)

Member Function Documentation

◆ computeCalculateFields()

void pcpp::IgmpV1Layer::computeCalculateFields ( )

Calculate the IGMP checksum and set igmp_header::maxResponseTime to 0 (this field is unused in IGMPv1)

Implements pcpp::Layer.
