It is especially well suited for continuous transmission of data. QTcpSocket is a convenience subclass of QAbstractSocket that allows you to establish a TCP connection and transfer streams of data. See the QAbstractSocket documentation for details. \bold{Note:} TCP sockets cannot be opened in QIODevice::Unbuffered mode. \sa QTcpServer, QUdpSocket, QNetworkAccessManager, {Fortune Server Example}, {Fortune Client Example}, {Threaded Fortune Server Example}, {Blocking Fortune Client Example}, {Loopback Example}, {Torrent Example} */ #include "qlist.h" #include "qtcpsocket_p.h" #include "qtcpsocket.h" #include "qhostaddress.h" QT_BEGIN_NAMESPACE /*!
