Detailed Description

This class provides description of ITS UDP/IP protocol layer.

Constructor & Destructor Documentation

udp_layer()

udp_layer::udp_layer	(	const std::string &	p_type,
		const std::string &	p_param
	)

Specialised constructor Create a new instance of the udp_layer class.

Parameters

[in]

p_type

~udp_layer()

virtual udp_layer::~udp_layer ( )

inlinevirtual

Default destructor.

Member Function Documentation

inet_check_sum()

unsigned short udp_layer::inet_check_sum ( const void *  buf, size_t  hdr_len, const unsigned short  p_initial_sum = 0  )

private

Destination socket address description.

Compute the UDP checksum

Parameters

[in]	p_buffer	The data to be sent
[in]	p_header_length	The UDP header length
[in]	p_initial_sum	The initial checksum value. Default: 0

Returns

The checksum value

receive_data()

void udp_layer::receive_data ( OCTETSTRING &  data, Params &  params  )

virtual

Receive bytes formated data from the lower layers.

Parameters

[in]	p_data	The bytes formated data received
[in]	p_params	Some lower layers parameters values when data was received

Reimplemented from layer.

send_data()
