    \class QLlcpServer
    \brief The QLlcpServer class provides an NFC LLCP socket based server.
    \internal

    \ingroup connectivity-nfc
    \inmodule QtNfc

    This class makes it possible to accept incoming LLCP socket connections.

    Call listen() to have the server start listening for incoming connections on a specified port.
    The newConnection() signal is then emitted each time a client connects to the server.

    Call nextPendingConnection() to accept the pending connection as a connected QLlcpSocket. The
    function returns a pointer to a QLlcpSocket that can be used for communicating with the client.

    If an error occurs, serverError() returns the type of error, and errorString() can be called to
    get a human readable description of what happened.

    When listening for connections, the port which the server is listening on is available through
    serverPort().

    Calling close() makes QLlcpServer stop listening for incoming connections.
