Description

This is a specialized type of socket: the TCP socket.

It can be used to talk with third party applications because it is frequent that other simulators (ex. Simulink) support the TCP socket communication.

Member Function Documentation

◆ acceptClient()

ChSocketTCP * chrono::cosimul::ChSocketTCP::acceptClient ( std::string & clientHost )

Accepts a connecting client.

The address of the connected client is stored in the parameter (a server call)

◆ ReceiveBuffer()

int chrono::cosimul::ChSocketTCP::ReceiveBuffer	(	std::vector< char > &	dest_buf,
		int	bsize
	)

Receive a std::vector<char> (a buffer of bytes) from the connected host, without the header as in SendMessage (so one must know in advance the length of the buffer).

If the receiving buffer size is not =bsize, it will be resized before receiving.

Parameters

dest_buf	destination buffer - will be resized
bsize	size in bytes of expected received buffer.

◆ receiveMessage()

int chrono::cosimul::ChSocketTCP::receiveMessage ( std::string & message )

Receive a std::string from the connected host.

Note that the string size is handled automatically because there is an headed that tells the length of the string in bytes.

◆ SendBuffer()

int chrono::cosimul::ChSocketTCP::SendBuffer ( std::vector< char > & source_buf )

Send a std::vector<char> (a buffer of bytes) to the connected host, without the header as in SendMessage (so the receiver must know in advance the length of the buffer).

Parameters

source_buf source buffer

◆ sendMessage()

int chrono::cosimul::ChSocketTCP::sendMessage ( std::string & message )

Send a std::string to the connected host.
