I’m using TCP sockets and wonder, if there’s a possibility to get an automatic notification when one side of a socket is closed (even if the other side is crashed / not closed properly).

You generally have to do a read on the socket to reliably detect when the other side has closed (or crashed).

And a write, too, or else use TCP keepalives.  Otherwise a crashed client which is never sending anything will not send any error indication for you to read.
