|
47 \brief The QTcpSocket class provides a TCP socket. |
|
48 |
|
49 \reentrant |
|
50 \ingroup network |
|
51 \inmodule QtNetwork |
|
52 |
|
53 TCP (Transmission Control Protocol) is a reliable, |
|
54 stream-oriented, connection-oriented transport protocol. It is |
|
55 especially well suited for continuous transmission of data. |
|
56 |
|
57 QTcpSocket is a convenience subclass of QAbstractSocket that |
|
58 allows you to establish a TCP connection and transfer streams of |
|
59 data. See the QAbstractSocket documentation for details. |
|
60 |
|
61 \bold{Note:} TCP sockets cannot be opened in QIODevice::Unbuffered mode. |
