44
45 \brief The QTcpSocket class provides a TCP socket.
46
47 \reentrant
48 \ingroup network
49 \inmodule QtNetwork
50
51 TCP (Transmission Control Protocol) is a reliable,
52 stream-oriented, connection-oriented transport protocol. It is
53 especially well suited for continuous transmission of data.
54
55 QTcpSocket is a convenience subclass of QAbstractSocket that
56 allows you to establish a TCP connection and transfer streams of
57 data. See the QAbstractSocket documentation for details.
58
59 \note TCP sockets cannot be opened in QIODevice::Unbuffered mode.
