Detailed Description

A wrapper class for TCP options. This class does not create or modify TCP option records, but rather serves as a wrapper and provides useful methods for retrieving data from them

Constructor & Destructor Documentation

TcpOption()

pcpp::TcpOption::TcpOption ( uint8_t *  optionRawData )

inline

A c'tor for this class that gets a pointer to the option raw data (byte array)

Parameters

[in]

optionRawData

A pointer to the TCP option raw data

~TcpOption()

pcpp::TcpOption::~TcpOption ( )

inline

A d'tor for this class, currently does nothing

Member Function Documentation

getDataSize()

size_t pcpp::TcpOption::getDataSize ( ) const

inlinevirtual

Returns

The size of the record value (meaning the size of the 'V' part in TLV)

Implements pcpp::TLVRecord< uint8_t, uint8_t >.

getTcpOptionType()

TcpOptionType pcpp::TcpOption::getTcpOptionType ( ) const

inline

Returns

TCP option type casted as pcpp::TcpOptionType enum. If the data is null a value of TCPOPT_Unknown is returned

getTotalSize()

size_t pcpp::TcpOption::getTotalSize ( ) const

inlinevirtual

Returns

The total size of the TLV record (in bytes)

Implements pcpp::TLVRecord< uint8_t, uint8_t >.
