How to "CLEAR" data on QTcpSocket

[wirasto]

Can I clear data on tcpSocket without read it ?

I tried like this but still not working.

qDebug() << myTcpSocket->size(); //result 3229696
myTcpSocket->reset();
qDebug() << myTcpSocket->size(); //result 3229696

qDebug() << myTcpSocket->size(); //result 3229696
myTcpSocket->reset();
qDebug() << myTcpSocket->size(); //result 3229696

To copy to clipboard, switch view to plain text mode 

If like this, is working. But, make a delay if data size is big.

qDebug() << myTcpSocket->size(); //result 3229696
myTcpSocket->readAll();
qDebug() << myTcpSocket->size(); //result 0

qDebug() << myTcpSocket->size(); //result 3229696
myTcpSocket->readAll();
qDebug() << myTcpSocket->size(); //result 0

To copy to clipboard, switch view to plain text mode 

Thank's before..
