The callback's prototype is

(void)(*)(int, short, void*)

the second parameter indicates what kind of event(s) happen.

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
