Timeouts on TCP Dial

[Matt Joiner]

I'm looking to do TCP dials with timeouts and specify local address. I see there was some work done on this with DialOpt, and suggestions of DialTCPTimeout. What's the status of this? What's the best way to work around it in the meanwhile?

There's a Dialer <http://golang.org/pkg/net/#Dialer> for this. Example <http://play.golang.org/p/4Rssm1AvpD>:

d := &net.Dialer{Timeout: 3 * time.Second}
c, err := d.Dial("tcp", "localhost:81")

It already exists:

I believe that the OP wanted to specify the source IP of the TCP connection as well. In that case, Dialer can do it (as well as the timeout) but DialTimeout cannot. See the LocalAddr and Timeout fields of the net.Dialer struct.

Thanks all. Somehow I didn't notice Dialer in the net package, and it has what I need.
