inline

A constructor that creates the layer from an existing packet raw data

Parameters

[in]	data	A pointer to the raw data
[in]	dataLen	Size of the data in bytes
[in]	prevLayer	A pointer to the previous layer
[in]	packet	A pointer to the Packet instance where layer will be stored in

WakeOnLanLayer() [2/5]

pcpp::WakeOnLanLayer::WakeOnLanLayer ( const pcpp::MacAddress &  targetAddr )

explicit

Construct a new Wake On Lan Layer with provided values

Parameters

[in]

targetAddr

Target MAC address

WakeOnLanLayer() [3/5]

pcpp::WakeOnLanLayer::WakeOnLanLayer	(	const pcpp::MacAddress &	targetAddr,
		uint8_t *	password,
		uint8_t	len
	)

Construct a new Wake On Lan Layer with provided values

Parameters

[in]	targetAddr	Target MAC address
[in]	password	Password as array
[in]	len	Length of the password array, length of the password should be less than 6 bytes

WakeOnLanLayer() [4/5]

pcpp::WakeOnLanLayer::WakeOnLanLayer	(	const pcpp::MacAddress &	targetAddr,
		const pcpp::MacAddress &	password
	)

Construct a new Wake On Lan Layer with provided values

Parameters

Member Function Documentation

getHeaderLen()

size_t pcpp::WakeOnLanLayer::getHeaderLen ( ) const

inlineoverridevirtual

Returns

Get the size of the layer

Implements pcpp::Layer.

getOsiModelLayer()

OsiModelLayer pcpp::WakeOnLanLayer::getOsiModelLayer ( ) const

inlineoverridevirtual

Returns

The OSI layer level of Wake on LAN (Data Link Layer)

Implements pcpp::Layer.

getPassword()

std::string pcpp::WakeOnLanLayer::getPassword

(

)

const

Get the password of the command

Returns

Returns the password if exists, empty string otherwise

getTargetAddr()

pcpp::MacAddress pcpp::WakeOnLanLayer::getTargetAddr

(

)

const

Get the target MAC address of the command

Returns

MAC address of the target

getWakeOnLanHeader()

wol_header* pcpp::WakeOnLanLayer::getWakeOnLanHeader ( ) const

inline

Get a pointer to the Wake On LAN header. Notice this points directly to the data, so every change will change the actual packet data

Returns

A pointer to the wol_header

isDataValid()

static bool pcpp::WakeOnLanLayer::isDataValid ( const uint8_t *  data, size_t  dataSize  )

static

A static method that takes a byte array and detects whether it is a Wake on LAN message

Parameters

[in]	data	A byte array
[in]	dataSize	The byte array size (in bytes)

Returns

True if the data is identified as Wake on LAN message

isWakeOnLanPort()

static bool pcpp::WakeOnLanLayer::isWakeOnLanPort ( uint16_t  port )

inlinestatic

A static method that checks whether the port is considered as Wake on LAN

Parameters

[in]

port

The port number to be checked

setPassword() [1/4]

bool pcpp::WakeOnLanLayer::setPassword

(

const IPv4Address &

addr

)

Set the password of the command

Parameters

toString()

std::string pcpp::WakeOnLanLayer::toString ( ) const

overridevirtual

Returns

Returns the protocol info as readable string

Implements pcpp::Layer.
