\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.
