Member Function Documentation

getMulticastAddress()

IPv4Address pcpp::igmpv3_group_record::getMulticastAddress ( ) const

inline

Returns

The multicast address in igmpv3_group_record::multicastAddress as IPv4Address instance

getRecordLen()

size_t pcpp::igmpv3_group_record::getRecordLen

(

)

const

Returns

The total size in bytes of the group record

getSourceAddressAtIndex()

IPv4Address pcpp::igmpv3_group_record::getSourceAddressAtIndex

(

int

index

)

const

multicastAddress

uint32_t pcpp::igmpv3_group_record::multicastAddress

Contains the IP multicast address to which this Group Record pertains

numOfSources

uint16_t pcpp::igmpv3_group_record::numOfSources

Specifies how many source addresses are present in this Group Record

recordType

uint8_t pcpp::igmpv3_group_record::recordType

Group record type

sourceAddresses

uint8_t pcpp::igmpv3_group_record::sourceAddresses[]

A vector of n IP unicast addresses, where n is the value in this record's Number of Sources field
