Detailed Description

TCP/IP connection socket class.

Constructor & Destructor Documentation

constructor for client socket

Parameters

hostname	remote host name (or IP address)
port	port number to send packet

int rcsc::TCPSocket::connect ( )

make connection

int rcsc::TCPSocket::readFromStream	(	char *	buf,
		const std::size_t	len
	)

receive stream data from the connected remote host.

Parameters

buf	buffer to receive data
len	maximal length of buffer buf

Return values

0	error occured and errno is EWOULDBLOCK
-1	error occured

int rcsc::TCPSocket::writeToStream	(	const char *	data,
		const std::size_t	len
	)

send stream data to the connected host.

Parameters

data	the pointer to the data to be sent.
len	the length of data.
