QTcpSocket & livetime & deletion

[Dariusz]

Hey!

2 Cases
QTcpSocket = QTcpSocket::connectToHost()
and QTcpServer : nextPendingConnection()
Both of them are sockets with conections.
The question I have... if I deleteLater() the sockets, do the connection get automatically disconnected, or do they remain active?

Secondly if I set option, QAbstractSocket::KeepAliveOption, does the connection then remain active after I delete socket?

Just trying to understand some odd cases where I delete socket and my server/client still remains connected...

TIA

TCP will disconnect after a standard timout in lieu of an explicit close. setsockopt() can set the timeout.

@jsulm Silly me, I always went straight to QAbstractSocket from that page... thanks!
