I mean the error 'epoll'(or sth else) detected. for example, if a socket is closed by its peer, and the corresponding callback is invoked, how can the callback know that there is and error happened? try to read/write the socket first?

Because there is no 'EV_ERROR', you could not set this kind of event for detecting(as select). So, you don't have method or don't need detect ERR(please distinguish with err generated by read()) on a socket.

I found libevent-1.4.10 didn't have EV_ERROR. So my question is: When monitoring a socket, what value will be set to the second parameter if an error occurred on the socket? thanks *********************************************************************** To unsubscribe, send an e-mail to [email protected] with unsubscribe libevent-users in the body.
