pcpp::arphdr Struct Reference

#include <ArpLayer.h>

Public Attributes
uint16_t	hardwareType
	Hardware type (HTYPE)
uint16_t	protocolType
	Protocol type (PTYPE). The permitted PTYPE values share a numbering space with those for EtherType.
uint8_t	hardwareSize
	Hardware address length (HLEN). For IPv4, this has the value 0x0800.
uint8_t	protocolSize
uint16_t	opcode
uint8_t	senderMacAddr [6]
	Sender hardware address (SHA)
uint32_t	senderIpAddr
	Sender protocol address (SPA)
uint8_t	targetMacAddr [6]
	Target hardware address (THA)
uint32_t	targetIpAddr
	Target protocol address (TPA)

Detailed Description

Represents an ARP protocol header

Member Data Documentation

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
