◆ 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
