provides a TCP-based server.</p> <p>This class makes it possible to accept incoming TCP connections. You can specify the port or have QTcpServer pick one automatically. You can listen on a specific address or on all the machine's addresses.</p> <p>Call <a href="qtcpserver.html#listen">listen</a>() to have the server listen for incoming connections. The <a href="qtcpserver.html#newConnection">newConnection</a>() signal is then emitted each time a client connects to the server.</p> <p>Call <a href="qtcpserver.html#nextPendingConnection">nextPendingConnection</a>() to accept the pending connection as a connected <a href="qtcpsocket.html">QTcpSocket</a>. The function returns a pointer to a <a href="qtcpsocket.html">QTcpSocket</a> in <a href="qabstractsocket.html#SocketState-enum">QAbstractSocket::ConnectedState</a> that you can use for communicating with the client.</p> <p>If an error occurs, <a href="qtcpserver.html#serverError">serverError</a>() returns the type of error, and <a href="qtcpserver.html#errorString">errorString</a>() can be called to get a human readable description of what happened.</p> <p>When listening for connections, the address and port on which the server is listening are available as <a href="qtcpserver.html#serverAddress">serverAddress</a>() and <a href="qtcpserver.html#serverPort">serverPort</a>().</p> <p>Calling <a href="qtcpserver.html#close">close</a>() makes QTcpServer stop listening for incoming connections.</p> <p>Although QTcpServer is mostly designed for use with an event loop, it's possible to use it without one. In that case, you must use <a href="qtcpserver.html#waitForNewConnection">waitForNewConnection</a>(), which blocks until either a connection is available or a timeout expires.</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.
