在Golang中，如何使用通道处理许多goroutine

Question

I'm thinking start 1000 goroutines at the same time using for loop in Golang.
The problem is: I have to make sure that every goroutine has been executed.
Is it possible using channels to help me make sure of that?

The structure is kinda like this:

func main {
    for i ... {
        go ...
        ch?
    ch?
}
