  1. Golang

Golang For Slect

通常在 for 循环中,使用 break 可以跳出循环,但是注意在 Go 语言中,for select 配全时,break 并不能跳出循环。

func testSelectFor2(chExit chan bool){
 EXIT:
    for  {
        select {
        case v, ok := <-chExit:
            if !ok {
                fmt.Println("close channel 2", v)
                break EXIT//goto EXIT2
            }

            fmt.Println("ch2 val =", v)
        }
    }

    //EXIT2:
    fmt.Println("exit testSelectFor2")
}

// output 
// fatal error: all goroutines are asleep - deadlock!
