10 | | \brief The QTcpSocket class provides a TCP socket. |
11 | | |
12 | | \reentrant |
13 | | \ingroup network |
14 | | \inmodule QtNetwork |
15 | | |
16 | | TCP (Transmission Control Protocol) is a reliable, |
17 | | stream-oriented, connection-oriented transport protocol. It is |
18 | | especially well suited for continuous transmission of data. |
19 | | |
20 | | QTcpSocket is a convenience subclass of QAbstractSocket that |
21 | | allows you to establish a TCP connection and transfer streams of |
22 | | data. See the QAbstractSocket documentation for details. |
23 | | |
24 | | \note TCP sockets cannot be opened in \l QIODeviceBase::Unbuffered mode. |
