<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><b>Note:</b> TCP sockets cannot be opened in <a href="qiodevice.html#OpenModeFlag-enum">QIODevice::Unbuffered</a> mode.</p>
<a name="symbian-platform-security-requirements"></a>
<h3>Symbian Platform Security Requirements</h3>
<p>On Symbian, processes which use this class must have the <tt>NetworkServices</tt> platform security capability. If the client process lacks this capability, it will result in a panic.</p>
<p>Platform security capabilities are added via the <a href="qmake-variable-reference.html#target-capability">TARGET.CAPABILITY</a> qmake variable.</p>
