通知所有goroutine

Question

I am working on a TCP Server in Go. Now I want to notify all goroutines that are talking to clients to drop their connections, dump what they've got and stop.

Closing a channel is a way to notify all of them.

Question is: Is that idiomatic Go? If I am wrong; then what should I do (for notifying all of goroutines - something like ManualResetEvent in .NET)?

Note: I am a Go newbie, just learning and started with TCP Server because I have written that before in C#.

Answer 1

Yes, closing a channel is an idiomatic Go way of communicating between Goroutines.

You'll need to pass a channel into each goroutine as it launches and check the channel with the select call after each network event.

You'll also want to set timeouts on network events so that you don't have connections hanging around forever.
