Help using QUdpSocket in blocking mode without an event loop

[dbrmik]

Hi

Having problems using qudpsocket in blocking mode

My code is below, runs in a seperate thread

@
void run()
{

QUdpSocket s;
s.bind();

forever
{

//get data from other thread

//code to process data

//then send out on wire
qint64 n;
n = s.writeDatagram( buffer, len, QHostAddress("........."), port);
s.flush();
s.waitForBytesWritten(-1);

if (len != n)
          qDebug() << "Error sending data << qPrintable(s.errorString());

}
}

@

The code was originally written using bsd sockets using sendto (socket.h) in blocking mode.

The writeDatagram function function sometimes fails with QAbstractSocket::NetworkError, however the original sendto never failed

I suppose the bottom line is how do I make the QUdpSocket writeDatagram function work like socket.h sendto function?

Thanks

you could try waitForBytesWritten

Hi

Yes, if you look at the code you will see that I have tried that. What I dont understand is a way to make writeDatagram behave like socket.h function sendto in blocking mode.

Any help would be appreciated
