The TQServerSocket class provides a TCP-based server.
<p>
<p> This class is a convenience class for accepting incoming TCP
connections. You can specify the port or have TQServerSocket pick
one, and listen on just one address or on all the machine's
addresses.
<p> Using the API is very simple: subclass TQServerSocket, call the
constructor of your choice, and implement <a href="#newConnection">newConnection</a>() to
handle new incoming connections. There is nothing more to do.
<p> (Note that due to lack of support in the underlying APIs,
TQServerSocket cannot accept or reject connections conditionally.)
<p> <p>See also <a href="ntqsocket.html">TQSocket</a>, <a href="ntqsocketdevice.html">TQSocketDevice</a>, <a href="ntqhostaddress.html">TQHostAddress</a>, <a href="ntqsocketnotifier.html">TQSocketNotifier</a>, and <a href="io.html">Input/Output and Networking</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQServerSocket"></a>TQServerSocket::TQServerSocket ( Q_UINT16 port, int backlog = 1, <a href="ntqobject.html">TQObject</a> * parent = 0, const char * name = 0 )
</h3>
Creates a server socket object, that will serve the given <em>port</em>
on all the addresses of this host. If <em>port</em> is 0, TQServerSocket
will pick a suitable port in a system-dependent manner. Use <em>backlog</em> to specify how many pending connections the server can
have.
<p> The <em>parent</em> and <em>name</em> arguments are passed on to the <a href="ntqobject.html">TQObject</a>
constructor.
<p> <b>Warning:</b> On Tru64 Unix systems a value of 0 for <em>backlog</em> means
that you don't accept any connections at all; you should specify a
value larger than 0.
<h3 class=fn><a name="TQServerSocket-2"></a>TQServerSocket::TQServerSocket ( const <a href="ntqhostaddress.html">TQHostAddress</a> & address, Q_UINT16 port, int backlog = 1, <a href="ntqobject.html">TQObject</a> * parent = 0, const char * name = 0 )
</h3>
Creates a server socket object, that will serve the given <em>port</em>
only on the given <em>address</em>. Use <em>backlog</em> to specify how many
pending connections the server can have.
<p> The <em>parent</em> and <em>name</em> arguments are passed on to the <a href="ntqobject.html">TQObject</a>
constructor.
<p> <b>Warning:</b> On Tru64 Unix systems a value of 0 for <em>backlog</em> means
that you don't accept any connections at all; you should specify a
value larger than 0.
<h3 class=fn><a name="TQServerSocket-3"></a>TQServerSocket::TQServerSocket ( <a href="ntqobject.html">TQObject</a> * parent = 0, const char * name = 0 )
</h3>
Construct an empty server socket.
<p> This constructor, in combination with <a href="#setSocket">setSocket</a>(), allows us to
use the TQServerSocket class as a wrapper for other socket types
(e.g. Unix Domain Sockets under Unix).
<p> The <em>parent</em> and <em>name</em> arguments are passed on to the <a href="ntqobject.html">TQObject</a>
constructor.
<p> <p>See also <a href="#setSocket">setSocket</a>().
<h3 class=fn><a name="~TQServerSocket"></a>TQServerSocket::~TQServerSocket ()<tt> [virtual]</tt>
</h3>
Destroys the socket.
<p> This causes any backlogged connections (connections that have
reached the host, but not yet been completely set up by calling
<a href="ntqsocketdevice.html#accept">TQSocketDevice::accept</a>()) to be severed.
<p> Existing connections continue to exist; this only affects the
acceptance of new connections.
<h3 class=fn><a href="ntqhostaddress.html">TQHostAddress</a> <a name="address"></a>TQServerSocket::address () const
</h3>
Returns the address on which this object listens, or 0.0.0.0 if
this object listens on more than one address. <a href="#ok">ok</a>() must be TRUE
before calling this function.
<p> <p>See also <a href="#port">port</a>() and <a href="ntqsocketdevice.html#address">TQSocketDevice::address</a>().
<h3 class=fn>void <a name="newConnection"></a>TQServerSocket::newConnection ( int socket )<tt> [pure virtual]</tt>
</h3>
<p> This pure virtual function is responsible for setting up a new
incoming connection. <em>socket</em> is the fd (file descriptor) for the
newly accepted connection.
<h3 class=fn>bool <a name="ok"></a>TQServerSocket::ok () const
</h3>
Returns TRUE if the construction succeeded; otherwise returns FALSE.
<h3 class=fn>Q_UINT16 <a name="port"></a>TQServerSocket::port () const
</h3>
Returns the port number on which this server socket listens. This
is always non-zero; if you specify 0 in the constructor,
TQServerSocket will pick a non-zero port itself. <a href="#ok">ok</a>() must be TRUE
before calling this function.
<p> <p>See also <a href="#address">address</a>() and <a href="ntqsocketdevice.html#port">TQSocketDevice::port</a>().
<p>Example: <a href="httpd-example.html#x726">network/httpd/httpd.cpp</a>.
<h3 class=fn>void <a name="setSocket"></a>TQServerSocket::setSocket ( int socket )<tt> [virtual]</tt>
</h3>
Sets the socket to use <em>socket</em>. bind() and listen() should
already have been called for <em>socket</em>.
<p> This allows us to use the TQServerSocket class as a wrapper for
other socket types (e.g. Unix Domain Sockets).
<h3 class=fn>int <a name="socket"></a>TQServerSocket::socket () const
</h3>
Returns the operating system socket.
<h3 class=fn><a href="ntqsocketdevice.html">TQSocketDevice</a> * <a name="socketDevice"></a>TQServerSocket::socketDevice ()<tt> [protected]</tt>
</h3>
Returns a pointer to the internal socket device. The returned
pointer is 0 if there is no connection or pending connection.
<p> There is normally no need to manipulate the socket device directly
since this class does all the necessary setup for most client or
server socket applications.
