nsIServerSocket Interface

 asyncListen

 This method puts the server socket in the listening state.  It will
 asynchronously listen for and accept client connections.  The listener
 will be notified once for each client connection that is accepted.  The
 listener's onSocketAccepted method will be called on the same thread
 that called asyncListen (the calling thread must have a nsIEventTarget).

 The listener will be passed a reference to an already connected socket
 transport (nsISocketTransport).  See below for more details.

 @param aListener
        The listener to be notified when client connections are accepted.

void asyncListen(in nsIServerSocketListener aListener)

 close

 This method closes a server socket.  This does not affect already
 connected client sockets (i.e., the nsISocketTransport instances
 created from this server socket).  This will cause the onStopListening
 event to asynchronously fire with a status of NS_BINDING_ABORTED.

void close()

 Returns the address to which this server socket is bound.  Since a
 server socket may be bound to multiple network devices, this address
 may not necessarily be specific to a single network device.  In the
 case of an IP socket, the IP address field would be zerod out to
 indicate a server socket bound to all network devices.  Therefore,
 this method cannot be used to determine the IP address of the local
 system.  See nsIDNSService::myHostName if this is what you need.

 init

 This method initializes a server socket.

 @param aPort
        The port of the server socket.  Pass -1 to indicate no preference,
        and a port will be selected automatically.
 @param aLoopbackOnly
        If true, the server socket will only respond to connections on the
        local loopback interface.  Otherwise, it will accept connections
        from any interface.  To specify a particular network interface,
        use initWithAddress.
 @param aBackLog
        The maximum length the queue of pending connections may grow to.
        This parameter may be silently limited by the operating system.
        Pass -1 to use the default value.

void init(in long aPort, in boolean aLoopbackOnly, in long aBackLog)

 initWithAddress

 This method initializes a server socket, and binds it to a particular
 local address (and hence a particular local network interface).

 @param aAddr
        The address to which this server socket should be bound.
 @param aBackLog
        The maximum length the queue of pending connections may grow to.
        This parameter may be silently limited by the operating system.
        Pass -1 to use the default value.
