help with readyRead() signal "mechanics"

[danadam]

Hello!

I admit that I'm not a qt expert but I guess that signal is emitted every time a TCP segment is received. And TCP stack at client side decides how many bytes will be in that segment. So if client wants to send ie. 100 bytes of data, that it can be received at server side all in one segment (and one signal will be emitted) or in 2 segments (and two signals will be emitted) or in 3 segments, etc..

Thats sounds logical, thanks.
With your comment, the docs make more sense to me now:

void QIODevice::readyRead () [signal]

This signal is emitted once every time new data is available for reading from the device. It will only be emitted again once new data is available, such as when a new payload of network data has arrived on your network socket, or when a new block of data has been appended to your device.

readyRead() is not emitted recursively; if you reenter the event loop or call waitForReadyRead() inside a slot connected to the readyRead() signal, the signal will not be reemitted (although waitForReadyRead() may still return true).
