How to know that binding local address is done?

[simon-fu]

If app listens only on local, how to know that all of SwarmEvent::NewListenAddr have received?

when the binding process is complete, you need to use the SwarmEvent::NewListenAddr event, which is emitted by the Swarm::poll method. This event is emitted when a new local listen address has been successfully bound.

Yes, I do know what SwarmEvent::NewListenAddr event means. My question is how do I know that all of SwarmEvent::NewListenAddr events have been emitted ? Is there any event like "SwarmEvent::LocalBindFinished" ?

[kehiy]

no, that seems there is no SwarmEvent::LocalBindFinished!

What does "done" mean? Most operating systems support dynamic creation and removal of interfaces so how would we know when we are "done"?

We will dynamically bind to all available interfaces as they become available if you listen on a wildcard address. If you don't want that, you should bind to a specific interface.

Got it. Thanks a lot.
