如何声明runtime.LockOSThread（）和runtime.UnlockOSThread（）

Question

I could not able to find how to declare runtime.LockOSThread() and runtime.UnlockOSThread(). I define it like [runtime.LockOSThread()] some code [runtime.UnlockOSThread()]. But it is giving error,undefined: runtime.LockOSThread and undefined: runtime.UnlockOSThread. Can anybody suggest me how to define it ? For more, I define it like,

Routine 1 {
runtime.LockOSThread()
do something
runtime.UnlockOSThread

}

main {
routine1
}

Answer 1

For example,

package main

import "runtime"

func routine() {
    runtime.LockOSThread()
    runtime.UnlockOSThread()
}

func main() {
    go routine()
}
