+.SH DESCRIPTION
+The QServerSocket class provides a TCP-based server.
+.PP
+This class is a convenience class for accepting incoming TCP connections. You can specify the port or have QServerSocket pick one, and listen on just one address or on all the machine's addresses.
+.PP
+Using the API is very simple: subclass QServerSocket, call the constructor of your choice, and implement newConnection() to handle new incoming connections. There is nothing more to do.
+.PP
+(Note that due to lack of support in the underlying APIs, QServerSocket cannot accept or reject connections conditionally.)
+.PP
+See also QSocket, QSocketDevice, QHostAddress, QSocketNotifier, and Input/Output and Networking.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QServerSocket::QServerSocket ( Q_UINT16 port, int backlog = 1, QObject * parent = 0, const char * name = 0 )"
+Creates a server socket object, that will serve the given \fIport\fR on all the addresses of this host. If \fIport\fR is 0, QServerSocket will pick a suitable port in a system-dependent manner. Use \fIbacklog\fR to specify how many pending connections the server can have.
+.PP
+The \fIparent\fR and \fIname\fR arguments are passed on to the QObject constructor.
+.PP
+\fBWarning:\fR On Tru64 Unix systems a value of 0 for \fIbacklog\fR means that you don't accept any connections at all; you should specify a value larger than 0.
+.SH "QServerSocket::QServerSocket ( const QHostAddress & address, Q_UINT16 port, int backlog = 1, QObject * parent = 0, const char * name = 0 )"
+Creates a server socket object, that will serve the given \fIport\fR only on the given \fIaddress\fR. Use \fIbacklog\fR to specify how many pending connections the server can have.
+.PP
+The \fIparent\fR and \fIname\fR arguments are passed on to the QObject constructor.
+.PP
+\fBWarning:\fR On Tru64 Unix systems a value of 0 for \fIbacklog\fR means that you don't accept any connections at all; you should specify a value larger than 0.
+.SH "QServerSocket::QServerSocket ( QObject * parent = 0, const char * name = 0 )"
+Construct an empty server socket.
+.PP
+This constructor, in combination with setSocket(), allows us to use the QServerSocket class as a wrapper for other socket types (e.g. Unix Domain Sockets under Unix).
+.PP
+The \fIparent\fR and \fIname\fR arguments are passed on to the QObject constructor.
+.PP
+See also setSocket().
+.SH "QServerSocket::~QServerSocket ()\fC [virtual]\fR"
+Destroys the socket.
+.PP
+This causes any backlogged connections (connections that have reached the host, but not yet been completely set up by calling QSocketDevice::accept()) to be severed.
+.PP
+Existing connections continue to exist; this only affects the acceptance of new connections.
+.SH "QHostAddress QServerSocket::address () const"
+Returns the address on which this object listens, or 0.0.0.0 if this object listens on more than one address. ok() must be TRUE before calling this function.
+.PP
+See also port() and QSocketDevice::address().
+.SH "void QServerSocket::newConnection ( int socket )\fC [pure virtual]\fR"
+This pure virtual function is responsible for setting up a new incoming connection. \fIsocket\fR is the fd (file descriptor) for the newly accepted connection.
+.SH "bool QServerSocket::ok () const"
+Returns TRUE if the construction succeeded; otherwise returns FALSE.
+.SH "Q_UINT16 QServerSocket::port () const"
+Returns the port number on which this server socket listens. This is always non-zero; if you specify 0 in the constructor, QServerSocket will pick a non-zero port itself. ok() must be TRUE before calling this function.
+.PP
+See also address() and QSocketDevice::port().
+.PP
+Example: network/httpd/httpd.cpp.
+.SH "void QServerSocket::setSocket ( int socket )\fC [virtual]\fR"
+Sets the socket to use \fIsocket\fR. bind() and listen() should already have been called for \fIsocket\fR.
+.PP
+This allows us to use the QServerSocket class as a wrapper for other socket types (e.g. Unix Domain Sockets).
+.SH "int QServerSocket::socket () const"
+Returns the operating system socket.
+.SH "QSocketDevice * QServerSocket::socketDevice ()\fC [protected]\fR"
+Returns a pointer to the internal socket device. The returned pointer is 0 if there is no connection or pending connection.
+.PP
+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.
