如何声明runtime.LockOSThread（）和runtime.

Question

我找不到如何声明runtime.LockOSThread（）和runtime.UnlockOSThread（）的方法。我像[runtime.LockOSThread（）]那样定义一些代码[runtime.UnlockOSThread（）]。但是它给出了错误，未定义：runtime.LockOSThread和未定义：runtime.UnlockOSThread。有人可以建议我如何定义它吗？对于更多，我将其定义为Routine 1 {runtime.LockOSThread()do somethingruntime.UnlockOSThread}main {routine1}

Answer 1

例如，

package main

import "runtime"

func routine() {

    runtime.LockOSThread()

    runtime.UnlockOSThread()

}

func main() {

    go routine()

}

如有疑问，请参阅文档。

func LockOSThread()

LockOSThread wires the calling goroutine to its current operating system thread.

Until the calling goroutine exits or calls UnlockOSThread, it will always execute in

that thread, and no other goroutine can.

func UnlockOSThread()

UnlockOSThread unwires the calling goroutine from its fixed operating system thread.

If the calling goroutine has not called LockOSThread, UnlockOSThread is a no-op.
