Member Data Documentation

hardwareSize

uint8_t pcpp::arphdr::hardwareSize

Hardware address length (HLEN). For IPv4, this has the value 0x0800

hardwareType

uint16_t pcpp::arphdr::hardwareType

Hardware type (HTYPE)

opcode

uint16_t pcpp::arphdr::opcode

Specifies the operation that the sender is performing: 1 (ARP_REQUEST) for request, 2 (ARP_REPLY) for reply

protocolSize

uint8_t pcpp::arphdr::protocolSize

Protocol length (PLEN). Length (in octets) of addresses used in the upper layer protocol. (The upper layer protocol specified in PTYPE.) IPv4 address size is 4

protocolType

uint16_t pcpp::arphdr::protocolType

Protocol type (PTYPE). The permitted PTYPE values share a numbering space with those for EtherType

senderIpAddr

uint32_t pcpp::arphdr::senderIpAddr

Sender protocol address (SPA)

senderMacAddr

uint8_t pcpp::arphdr::senderMacAddr[6]

Sender hardware address (SHA)

targetIpAddr

uint32_t pcpp::arphdr::targetIpAddr

Target protocol address (TPA)

targetMacAddr

uint8_t pcpp::arphdr::targetMacAddr[6]

Target hardware address (THA)
