Windows 7 清理 C++ 内存泄漏? [英] Windows 7 cleans up C++ memory leaks?

问题描述

只是为了好玩，我创建了一个项目，该项目创建了大约 5 GB 的内存并且没有删除它.只要应用程序正在运行，就会存在内存泄漏".当我关闭应用程序时，内存在 2 秒内恢复正常，就好像我的程序从未运行过一样.所以必须提出问题.

Just for fun I created a project that created about 5 GB of memory and did not delete it. As long as the application is running that "memory leak" is there. The second I close my application the memory within 2 seconds is back down to normal as if my program never ran. So the questions have to be asked.

Windows 7 是否会在不良程序完成后清理内存泄漏?

Does Windows 7 clean up memory leaks from bad programs when they are done?

所有 Windows 版本都这样做吗?

Do all Windows versions do this?

Linux 和 Mac OS X 环境会这样做吗?

Will Linux and Mac OS X environments do this?

推荐答案

当程序终止时，操作系统会回收之前分配给它的所有内存.清理内存泄漏可能是这种感知的副产品，但操作系统实际上并不这么认为.它不知道程序一直在泄漏内存，只知道它已经分配了它.

When the program terminates, the operating system reclaims all the memory that had previously been allocated to it. Cleaning up memory leaks may be a perceived by-product of this, but the OS does not actually see it that way. It does not know that the program had been leaking memory, just that it had allocated it.
