Member Function Documentation

◆ getMulticastAddress()

IPv4Address pcpp::igmpv3_group_record::getMulticastAddress ( ) const
The multicast address in igmpv3_group_record::multicastAddress as IPv4Address instance

◆ getRecordLen()

size_t pcpp::igmpv3_group_record::getRecordLen ( ) const
The total size in bytes of the group record

◆ getSourceAddressAtIndex()

IPv4Address pcpp::igmpv3_group_record::getSourceAddressAtIndex ( int  index) const

Get the source address at a certain index

[in]indexThe index of the source address in the group record
The source address in the requested index. If index is negative or higher than the number of source addresses in this group record the value if IPv4Address::Zero is returned

◆ getSourceAddressCount()

uint16_t pcpp::igmpv3_group_record::getSourceAddressCount ( ) const
The number of source addresses in this group record

Member Data Documentation

◆ auxDataLen

uint8_t pcpp::igmpv3_group_record::auxDataLen

Contains the length of the Auxiliary Data field in this Group Record. A value other than 0 isn't supported

◆ 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
