OK复制CRITICAL_SECTION？ [英] OK to copy a CRITICAL_SECTION?

问题描述

我们可以使用一个CRITICAL_SECTION变量获得互斥。

One can use a CRITICAL_SECTION variable to get mutual exclusion.

我的问题是：CRITICAL_SECTION支持复制？如果我传递一个由价值到另一个线程，我知道肯定互斥是否行得通呢？

My question is: does CRITICAL_SECTION support copying? If I pass one by value to another thread, can I know for sure that mutual exclusion will work?

我也不会感到惊讶，如果答案是你不能这样做，但它会是不错的具有某种官方的确认。我没能找到一份声明中的文档中任何一种方式。

I wouldn't be surprised if the answer is "you cannot do that", but it'd be nice to have some sort of official confirmation. I wasn't able to find a statement either way in the documentation.

推荐答案

没有。 A CRITICAL_SECTION 无法复制。 MSDN这个国家明确的：

No. A CRITICAL_SECTION cannot be copied. MSDN states this explicitly:

一个关键节对象不能移动或复制。

A critical section object cannot be moved or copied.
