\brief The QTcpSocket class provides a TCP socket.
39
TCP (Transmission Control Protocol) is a reliable,
40
stream-oriented, connection-oriented transport protocol. It is
41
especially well suited for continuous transmission of data.
43
QTcpSocket is a convenience subclass of QAbstractSocket that
44
allows you to establish a TCP connection and transfer streams of
45
data. See the QAbstractSocket documentation for details.

\l{network/fortuneclient}{Fortune Client},
49
\l{network/threadedfortuneserver}{Threaded Fortune Server}, and
50
\l{network/blockingfortuneclient}{Blocking Fortune Client}
51
examples illustrate how to use QTcpSocket in applications.
