A goroutine is a function which usually runs concurrently with other functions. If you want to stop goroutine, you pass a signal channel to the goroutine, that signal channel pushes a value into when you want the goroutine to stop.
The goroutine polls that channel regularly as soon as it detects a signal, it quits.
Quit : = make (chan bool)
go func ( ) {
for {
select {
case <- quit:
return
default
// do other stuff
}
}
}()
// Do stuff
// Quit goroutine
Quit <- true
