<h2>Detailed Description</h2>

<p>The QTcpSocket class provides a TCP socket.</p>

<p>TCP (Transmission Control Protocol) is a reliable, stream-oriented, connection-oriented transport protocol. It is especially well suited for continuous transmission of data.</p>

<p>QTcpSocket is a convenience subclass of <a href="qabstractsocket.html">QAbstractSocket</a> that allows you to establish a TCP connection and transfer streams of data. See the <a href="qabstractsocket.html">QAbstractSocket</a> documentation for details.</p>

<p>The <a href="network-fortuneserver.html">Fortune Server</a>, <a href="network-fortuneclient.html">Fortune Client</a>, <a href="network-threadedfortuneserver.html">Threaded Fortune Server</a>, and <a href="network-blockingfortuneclient.html">Blocking Fortune Client</a> examples illustrate how to use QTcpSocket in applications.</p>

<h2>Member Function Documentation</h2>

<h3 class="fn"><a name="QTcpSocket"></a>QTcpSocket::QTcpSocket ( <a href="qobject.html">QObject</a> * <i>parent</i> = 0 )</h3>

<p>Creates a <a href="qtcpsocket.html">QTcpSocket</a> object in state <tt>UnconnectedState</tt>.</p>

<p><i>parent</i> is passed on to the <a href="qobject.html">QObject</a> constructor.</p>

<p>See also <a href="qabstractsocket.html#socketType">socketType</a>().</p>

<h3 class="fn"><a name="dtor.QTcpSocket"></a>QTcpSocket::~QTcpSocket ()  <tt> [virtual]</tt></h3>

<p>Destroys the socket, closing the connection if necessary.</p>
