I'm implement a function that would call an interrupt signal in Go, using something like this for capturing interrupt signal
var stopChan = make(chan os.Signal, 2)
signal.Notify(stopChan, os.Interrupt, syscall.SIGTERM, syscall.SIGINT)
<-stopChan // wait for SIGINT
Use below from anywhere in your code to send interrupt signal to above wait part.
Or if you are in the same package where where stopChan variable is defined. Thus making it accessible. You can do this.
stopChan <- syscall.SIGINT
Or you can define stopChan as a global variable (making the first letter in Capital letter will achieve the same), then you can send interrupt signal from a different package too.
Stopchan <- syscall.SIGINT
