|

| 47 | \brief The QTcpSocket class provides a TCP socket.
|
|---|

|

| 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.

| 63 | \section1 Symbian Platform Security Requirements
|
|---|
| 64 |
|
|---|
| 65 | On Symbian, processes which use this class must have the
|
|---|
| 66 | \c NetworkServices platform security capability. If the client
|
|---|
| 67 | process lacks this capability, it will result in a panic.
|
|---|
| 68 |
|
|---|
| 69 | Platform security capabilities are added via the
|
|---|
| 70 | \l{qmake-variable-reference.html#target-capability}{TARGET.CAPABILITY}
|
|---|
| 71 | qmake variable.
