\class QTcpSocket

\brief The QTcpSocket class provides a TCP socket.

\reentrant

\ingroup network

\inmodule QtNetwork

TCP (Transmission Control Protocol) is a reliable,

stream-oriented, connection-oriented transport protocol. It is

especially well suited for continuous transmission of data.

QTcpSocket is a convenience subclass of QAbstractSocket that

allows you to establish a TCP connection and transfer streams of

data. See the QAbstractSocket documentation for details.

\note TCP sockets cannot be opened in QIODevice::Unbuffered mode.
