You're correct in that it is reliable under the hood. The problem is really
just that most TCP APIs don't expose to the app what has been acknowledged. It
is pretty sad that everyone solves this by layering acks on top, when acks are
already being performed a layer down.
I think it would be nea
AFAIK, that numbering is done by the OS itself and is not intended to be
accessed/used by applications.

Are you sure it isn't just Qt failing to utilize the TCP protocol
correctly? I don't mean to question your expertise, as you sound like
you know what you're talking about, but this quote from wikipedia
makes it sound like TCP does in fact do
Hi,
It is not possible to know what TCP data has been acked through QTcpSocket
alone. The bytesWritten signal is more for flow-control. Generally speaking,
TCP is designed to make it easier to send data, but TCP alone is generally not
a solution for reliable transmission. It is possible to dete
So after some more reading/testing, I'm starting to think
QIODevice::bytesWritten(qint64) might be what I'm looking for... but I
am unable to confirm it.
There's only one tiny snippet in the QAbstractSocket docs that
indicate the bytesWritten(qint64) might be a TCP ACK for that amount
of bytes: "T
Thanks Nikos and Soroush (you replied to me instead to the list).
I can't really explain why it happened. But I removed the QtCreator's
configurations and create another one pointing to the same place and
fonts are back to normal again. Strange because I wasn't using anything
related to Qt. I t
