Reading from multiple channels simultaneously in Golang

Question

I am new to Golang. Right now I am trying to figure out how to make an any-to-one channel in Golang, where the setup is as follows:

say I have two goroutines numgen1

To answer the question "Reading from multiple channels simultaneously"

There is a way to listen to multiple channels simultaneously :

func main() {

    c1 := make(chan string)
    c2 := make(chan string)

    ...
    go func() {
        for {
            select {
                case msg1 := <- c1:
                fmt.Println(msg1)

                case msg2 := <- c2:
                fmt.Println(msg2)
             }
        }
    }()

In this example, I create a channel msg1 and msg2. Then I create a go routine with an infinite loop. In this loop, I listen to msg1 AND msg2. This system allow you to read to multiple channels simultaneously and to process the messages when the arrive.

In order to avoid leaks, I should probably add another channel to stop the goroutine.
