如何聲明runtime.LockOSThread（）和runtime.UnlockOSThread（）

Question

我無法找到如何聲明runtime.LockOSThread()和runtime.UnlockOSThread()。我將它定義爲[runtime.LockOSThread（）]一些代碼[runtime.UnlockOSThread（）]。但它給錯誤，未定義：runtime.LockOSThread和undefined：runtime.UnlockOSThread。任何人都可以建議我如何定義它？欲瞭解更多，我將它定義爲，

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

} 

main { 
routine1 
} 

Answer 1

例如，

package main 

import "runtime" 

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

func main() { 
    go routine() 
} 

Answer 2

如有疑問，請參閱the documentation。

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.
