Detecting QLocalSocket closing

Question

So I have 2 QT applications, one runs a QLocalServer and listens for a connection. Upon the other application (the client) connection it initializes a QLocalSocket. On the client side I just connect to the server. Is there any way for the client to detect when the server has closed? Right now if I close the server and the client keeps running, I get a SIGPIPE exception when I try to flush the socket.

Answer 1

Suppose you use sub-class inherited from QAbstractSocket, at least there are two way to handle connection lost.

SocketState QAbstractSocket::state() const ,

you could query the current state if you want. Second ,QAbstractSocket can trigger an signal :

void    disconnected()

then you can define your own slot to handle the disconnection.
