推荐答案

可能你不能 - 除了非常简单的系统外，操作系统不会让你靠近真正的内存。对于任何复杂的东西，它为您提供了一个虚拟地址空间，并且只允许您访问与您的线程相关的一些内存。



你想要什么？你认为你需要这个吗？

Probably, you can't - the operating system won't let you near the "real" memory except in very simple systems. For anything complex it provides you with a virtual address space and also only give you access to some of the memory - that associated with your thread.

What are you trying to do that you think you need this?
