digitalmars.D.learn - async socket programming in D?

I know the socket has the nonblocking settings, but how would I 
actually go around using it in D? Is there a specific procedure 
for it to work correctly etc.


I've taken a look at splat.d but it seems to be very outdated, so 
that's why I went ahead and asked here as I'd probably have to 
end up writing my own wrapper.

The "Socket" class has "blocking" property that is boolean. 
Before starting to listening as a server socket, or connecting to 
a server as client, if you set it to "false", then you can use 
them (waiting for client with `accept` or receiving messages) as 
asynchronous.

Already as you know, a client that is created from the `accept` 
method of non-blocking server socket is non-blocking as well. So 
you don't have to do anything about it.

I was actually working on this in a new event loop for vibe.d here: 
https://github.com/globecsys/vibe.d/tree/native-events/source/vibe/core/events

I've left it without activity for a week b/c I'm currently busy making a 
(closed source) SSL library to replace openSSL in my projects, but I'll 
return to this one project here within a couple weeks at most.

It doesn't build yet, but you can probably use some of it at least as a 
reference, it took me a while to harvest the info on windows and linux 
kernels for async I/O. Some interesting parts like that which you wanted 
are found here:
https://github.com/globecsys/vibe.d/blob/native-events/source/vibe/core/events/epoll.d#L403

I think I was at handling a new connection or incoming data though, so 
you won't find accept() or read callbacks, but with it I think it was 
pretty much ready for async TCP.

But of course, nothing stops you from using vibe.d with libevent ;)
