In nmathewson/libevent-book/blob/master/Ref4_event.txt under _constructing_signal_events there is a warning about setting timers from signal callback "It might not be supported".
I did a SIMPLE test and did not run into a problem, furthermore it would make sense for this to potentially be a problem in the signal handler itself, rather than the callback. I assume that the callback should be executing in the event-loop context and thus should be okay. In either case, IMO this should either go away or become more definitive, i.e. list cases, environments where it is not supported.
Thanks

at line 241 of Ref2, the flag for O1 event notification shall be EV_FEATURE_O1 instead of EV_FEATURE_ET ?
if ((f & EV_FEATURE_ET))
printf(" Edge-triggered events are supported.");
if ((f & EV_FEATURE_ET)) <- EV_FEATURE_O1 ?
printf(" O(1) event notification is supported.");
if ((f & EV_FEATURE_FDS))
Seems like there is a problem with asciidoc 8.6.3

Hey,
This bufferevent_base_connect()
function is mentionned in the book around here https://github.com/nmathewson/libevent-book/blob/9e9e5242f6fcd4cc6bfe564c22756ab6f5ce5914/Ref6_bufferevent.txt#L296
I can not find any other occurence of it in the book or in the libevent api.
Should I be reading bufferevent_socket_connect()
instead ?
Hi,
I think that the following is right.
The return value from evutil_inet_pton() is 1 on success, -1 on invalid af, and 0 on invalid address format.
In file "01intro.txt"
/* Add all of the interesting fds to readset */
for (i=0; i < n_sockets; ++i) {
if (fd[i]>maxfd) maxfd = fd[i];
FD_SET(i, &readset);
}
Should it be FD_SET(fd[i], &readset)? I'm not sure about it.
Here: https://github.com/nmathewson/libevent-book/blob/master/Ref6_bufferevent.txt#L271
The sockaddr_in is memset and the sin_addr and sin_port are set, but sin_family is not, leading to error 47 (Address family not supported by protocol family)
.

why named asynchronous IO?
In my opinion, asynchronous IO
is use like aio_write, aio_read
, but libevent use like epoll
, so there should use synchronous nonblocking IO
The "Working with events" sections mentions user-triggered events, but then doesn't discuss a canonical way of having user-triggered events.
Can this be added?
it is useful and I wanna take a try. Is it OK?
