\class QTcpSocket
|
|
|
|
\brief The QTcpSocket class provides a TCP socket.
|
|
|
|
\reentrant
|
|
\ingroup network
|
|
\inmodule QtNetwork
|
|
|
|
TCP (Transmission Control Protocol) is a reliable,
|
|
stream-oriented, connection-oriented transport protocol. 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.
|
|
|
|
\note TCP sockets cannot be opened in QIODevice::Unbuffered mode.
