<P>
<p>The <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> class provides the base functionality common to all socket types.</p>
<p><a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> is the base class for <a href="QTcpSocket.html"><tt>QTcpSocket</tt></a> and <a href="QUdpSocket.html"><tt>QUdpSocket</tt></a> and contains all common functionality of these two classes. If you need a socket, you have two options:</p>
<ul>
<li>Instantiate <a href="QTcpSocket.html"><tt>QTcpSocket</tt></a> or <a href="QUdpSocket.html"><tt>QUdpSocket</tt></a>.</li>
<li>Create a native socket descriptor, instantiate <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a>, and call <a href="QAbstractSocket.html#setSocketDescriptor(int, com.trolltech.qt.network.QAbstractSocket.SocketState, com.trolltech.qt.core.QIODevice.OpenMode)"><tt>setSocketDescriptor</tt></a> to wrap the native socket.</li>
</ul>
<p>TCP (Transmission Control Protocol) is a reliable, stream-oriented, connection-oriented transport protocol. UDP (User Datagram Protocol) is an unreliable, datagram-oriented, connectionless protocol. In practice, this means that TCP is better suited for continuous transmission of data, whereas the more lightweight UDP can be used when reliability isn't important.</p>
<p><a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a>'s API unifies most of the differences between the two protocols. For example, although UDP is connectionless, connectToHost() establishes a virtual connection for UDP sockets, enabling you to use <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> in more or less the same way regardless of the underlying protocol. Internally, <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> remembers the address and port passed to connectToHost(), and functions like <a href="%2E%2E/core/%2E%2E/core/QIODevice.html#read(long)"><tt>read</tt></a> and <a href="%2E%2E/core/%2E%2E/core/QIODevice.html#write(com.trolltech.qt.core.QByteArray)"><tt>write</tt></a> use these values.</p>
<p>At any time, <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> has a state (returned by <a href="QAbstractSocket.html#state()"><tt>state</tt></a>). The initial state is <a href="QAbstractSocket.html#SocketState-enum"><tt>UnconnectedState</tt></a>. After calling connectToHost(), the socket first enters <a href="QAbstractSocket.html#SocketState-enum"><tt>HostLookupState</tt></a>. If the host is found, <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> enters <a href="QAbstractSocket.html#SocketState-enum"><tt>ConnectingState</tt></a> and emits the <a href="QAbstractSocket.html#hostFound()"><tt>hostFound</tt></a> signal. When the connection has been established, it enters <a href="QAbstractSocket.html#SocketState-enum"><tt>ConnectedState</tt></a> and emits <a href="QAbstractSocket.html#connected()"><tt>connected</tt></a>. If an error occurs at any stage, <a href="QAbstractSocket.html#error()"><tt>error</tt></a> is emitted. Whenever the state changes, <a href="QAbstractSocket.html#stateChanged(com.trolltech.qt.network.QAbstractSocket.SocketState)"><tt>stateChanged</tt></a> is emitted. For convenience, <a href="QAbstractSocket.html#isValid()"><tt>isValid</tt></a> returns true if the socket is ready for reading and writing, but note that the socket's state must be <a href="QAbstractSocket.html#SocketState-enum"><tt>ConnectedState</tt></a> before reading and writing can occur.</p>
<p>Read or write data by calling <a href="%2E%2E/core/%2E%2E/core/QIODevice.html#read(long)"><tt>read</tt></a> or <a href="%2E%2E/core/%2E%2E/core/QIODevice.html#write(com.trolltech.qt.core.QByteArray)"><tt>write</tt></a>, or use the convenience functions <a href="%2E%2E/core/%2E%2E/core/QIODevice.html#readLine(long)"><tt>readLine</tt></a> and <a href="%2E%2E/core/%2E%2E/core/QIODevice.html#readAll()"><tt>readAll</tt></a>. <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> also inherits getChar(), putChar(), and ungetChar() from <a href="%2E%2E/core/%2E%2E/core/QIODevice.html#QIODevice(com.trolltech.qt.core.QObject)"><tt>QIODevice</tt></a>, which work on single bytes. For every chunk of data that has been written to the socket, the <a href="QAbstractSocket.html#bytesWritten(long)"><tt>bytesWritten</tt></a> signal is emitted.</p>
<p>The <a href="QAbstractSocket.html#readyRead()"><tt>readyRead</tt></a> signal is emitted every time a new chunk of data has arrived. <a href="QAbstractSocket.html#bytesAvailable()"><tt>bytesAvailable</tt></a> then returns the number of bytes that are available for reading. Typically, you would connect the <a href="QAbstractSocket.html#readyRead()"><tt>readyRead</tt></a> signal to a slot and read all available data there. If you don't read all the data at once, the remaining data will still be available later, and any new incoming data will be appended to <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a>'s internal read buffer. To limit the size of the read buffer, call <a href="QAbstractSocket.html#setReadBufferSize(long)"><tt>setReadBufferSize</tt></a>.</p>
<p>To close the socket, call <a href="QAbstractSocket.html#disconnectFromHost()"><tt>disconnectFromHost</tt></a>. <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> enters QAbstractSocket::ClosingState, then emits closing(). After all pending data has been written to the socket, <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> actually closes the socket, enters QAbstractSocket::ClosedState, and emits <a href="QAbstractSocket.html#disconnected()"><tt>disconnected</tt></a>. If you want to abort a connection immediately, discarding all pending data, call <a href="QAbstractSocket.html#abort()"><tt>abort</tt></a> instead. If the remote host closes the connection, <a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> will emit error(QAbstractSocket::RemoteHostClosedError), during which the socket state will still be <a href="QAbstractSocket.html#SocketState-enum"><tt>ConnectedState</tt></a>, and then the <a href="QAbstractSocket.html#disconnected()"><tt>disconnected</tt></a> signal will be emitted.</p>
<p>The port and address of the connected peer is fetched by calling peerPort() and <a href="QAbstractSocket.html#peerAddress()"><tt>peerAddress</tt></a>. <a href="QAbstractSocket.html#peerName()"><tt>peerName</tt></a> returns the host name of the peer, as passed to connectToHost(). localPort() and <a href="QAbstractSocket.html#localAddress()"><tt>localAddress</tt></a> return the port and address of the local socket.</p>
<p><a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> provides a set of functions that suspend the calling thread until certain signals are emitted. These functions can be used to implement blocking sockets:</p>
<ul>
<li><a href="QAbstractSocket.html#waitForConnected(int)"><tt>waitForConnected</tt></a> blocks until a connection has been established.</li>
<li><a href="QAbstractSocket.html#waitForReadyRead(int)"><tt>waitForReadyRead</tt></a> blocks until new data is available for reading.</li>
<li><a href="QAbstractSocket.html#waitForBytesWritten(int)"><tt>waitForBytesWritten</tt></a> blocks until one payload of data has been written to the socket.</li>
<li><a href="QAbstractSocket.html#waitForDisconnected(int)"><tt>waitForDisconnected</tt></a> blocks until the connection has closed.</li>
</ul>
<p>We show an example:</p>
<pre> int numRead = 0, numReadTotal = 0;
char buffer[50];
forever {
numRead = socket.read(buffer, 50);
<span class="comment">// do whatever with array</span>
numReadTotal += numRead;
if (numRead == 0 && !socket.waitForReadyRead())
break;
}</pre>
<p>If waitForReadyRead() returns false, the connection has been closed or an error has occurred.</p>
<p>Programming with a blocking socket is radically different from programming with a non-blocking socket. A blocking socket doesn't require an event loop and typically leads to simpler code. However, in a GUI application, blocking sockets should only be used in non-GUI threads, to avoid freezing the user interface. See the network/fortuneclient</tt> and network/blockingfortuneclient</tt> examples for an overview of both approaches.</p>
<p><a href="QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)"><tt>QAbstractSocket</tt></a> can be used with <a href="%2E%2E/core/QTextStream.html"><tt>QTextStream</tt></a> and <a href="%2E%2E/core/QDataStream.html"><tt>QDataStream</tt></a>'s stream operators (operator<<() and operator>>()). There is one issue to be aware of, though: You must make sure that enough data is available before attempting to read it using operator>>().</p>

<DL>
<DD>Attempts to make a connection to <tt>host</tt> on the given <tt>port</tt>.
<p>
The socket is opened in the given <tt>mode</tt> and first enters
HostLookupState, then performs a host name lookup of <tt>host</tt>.
If the lookup succeeds, hostFound() is emitted and QAbstractSocket
enters ConnectingState. It then attempts to connect to the address
or addresses returned by the lookup. Finally, if a connection is
established, QAbstractSocket enters ConnectedState and
emits connected().
<p>
At any point, the socket can emit error() to signal that an error
occurred.
<p>
<tt>host</tt> may be an IP address in string form (e.g.,
"43.195.83.32"), or it may be a host name (e.g.,
"www.trolltech.com"). QAbstractSocket will do a lookup only if
required. <tt>port</tt> is in native byte order.
