Answer 1

you can use a buffer field to hold the unfinished data temporarily and handle packets as they complete:

{
    while (socket->bytesAvailable())
    {
        buffer.append(socket->readAll());
        int packetSize = getPacketSize(buffer);
        while(packetSize>0)
        {
            handlePacket(buffer.left(packetSize);
            buffer.remove(0,packetSize);
            packetSize = getPacketSize(buffer);
        }
    }
}
