Two bind() calls

[Emerson Espínola]

Hi,

I'm trying to listen for datagrams in 2 address.

var dgram = require('dgram');
var server = dgram.createSocket("udp4");
server.bind(8001, "192.168.65.66");
server.bind(8001, "192.168.33.34");

I'm always able to bind to the first address, but with the second I always get error:
node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: bind Unknown system errno 10038
    at errnoException (dgram.js:352:11)
    at dgram.js:123:15
    at lookup (dgram.js:49:12)
    at UDP.lookup4 [as lookup] (dgram.js:59:10)
    at Socket.bind (dgram.js:120:16)
...

What am I doing wrong?

Have you tried listening on 2 different port. I don't think you can bind twice on the same port.

You need to create two socket objects, one for each address you want
to bind to. It's kind of odd that Windows reports it as 10038
(WSAENOTSOCK).

Thanks. It worked when I created two sockets objetcs.

That was a libuv-win bug. It has been fixed in libuv:
