Re: How to use a Unix Socket with type SOCK_DGRAM ?

[Iñaki Baz Castillo]

Now I'm sure that libuv does not support Unix Domain sockets with type
SOCK_DGRAM (AKA Unix datagram sockets):

https://github.com/joyent/libuv/blob/master/src/unix/stream.c#L925


I've also found a thread in the Node mailing list announcing the drop
of Unix datagram sockets (in 2011):

https://groups.google.com/forum/#!topic/nodejs/iCzhcuxGP1I

I expect that such an announcement should be done (or at least also)
in the libuv mailing list, rahter than just in the Node mailing list
(for all those libuv users not interested at all in Node).

Regards.

You can create the socket yourself, put it in non-blocking mode and
pass it uv_pipe_open.

That is not what you think.

I'm not sure if we had the mailing list back in the 0.6 days. Also,
back then node was probably the only libuv user.

My fault. libuv mailing list was created on 08/08/12.

Thanks a lot. Will check it.

To make things even more difficult I want unnamed pipes for
inter-thread communication, which means I will create both sockets
with socketpair() and won't call to bind on any of them.
