QSctpSocket::QSctpSocket(QObject *parent = nullptr)

Creates a QSctpSocket object in state UnconnectedState.

Sets the datagram operation mode. The parent argument is passed to QObject's constructor.

See also socketType() and setMaximumChannelCount().

[virtual] QSctpSocket::~QSctpSocket()

Destroys the socket, closing the connection if necessary.

See also close().

[override virtual] void QSctpSocket::close()

Reimplements: QAbstractSocket::close().

[override virtual] void QSctpSocket::disconnectFromHost()

Reimplements: QAbstractSocket::disconnectFromHost().

bool QSctpSocket::isInDatagramMode() const

Returns true if the socket is running in datagram mode.

See also setMaximumChannelCount().

int QSctpSocket::maximumChannelCount() const

Returns the maximum number of channels that QSctpSocket is able to support.

A value of 0 (the default) means that the number of connection channels would be set by the remote endpoint.

Returns -1 if QSctpSocket is running in continuous byte stream mode.

See also setMaximumChannelCount(), readChannelCount(), and writeChannelCount().

[override virtual protected] qint64 QSctpSocket::readData(char *data, qint64 maxSize)

Reimplements: QAbstractSocket::readData(char *data, qint64 maxSize).

QNetworkDatagram QSctpSocket::readDatagram()

Reads a datagram from the buffer of the current read channel, and returns it as a QNetworkDatagram object, along with the sender's host address and port. If possible, this function will also try to determine the datagram's destination address, port, and the number of hop counts at reception time.

On failure, returns a QNetworkDatagram that reports not valid.

See also writeDatagram(), isInDatagramMode(), and currentReadChannel().

[override virtual protected] qint64 QSctpSocket::readLineData(char *data, qint64 maxlen)

Reimplements: QAbstractSocket::readLineData(char *data, qint64 maxlen).

void QSctpSocket::setMaximumChannelCount(int count)

Sets the maximum number of channels that the application is prepared to support in datagram mode, to count. If count is 0, endpoint's value for maximum number of channels is used. Negative count sets a continuous byte stream mode.

Call this method only when QSctpSocket is in UnconnectedState.

See also maximumChannelCount(), readChannelCount(), and writeChannelCount().

bool QSctpSocket::writeDatagram(const QNetworkDatagram &datagram)

Writes a datagram to the buffer of the current write channel. Returns true on success; otherwise returns false.

See also readDatagram(), isInDatagramMode(), and currentWriteChannel().
