保存进程的内存以备后用? [英] Save a process' memory for later use?

问题描述

是否可以暂停进程，将内存内容保存到文件中，然后重新加载文件，以便继续执行程序?

Is it possible to pause a process, save the memory contents to a file, and then later reload the file so you can continue the program?

编辑我一直在读这个:

是否可以转储结构体的内容，并以某种方式强制 malloc 分配相同的内存区域?

Is it possible to dump the contents of the struct, and somehow force malloc to allocate the same memory regions?

推荐答案

从技术上讲这是可能的，但它也需要保存所有系统分配的资源状态 - 例如文件描述符，然后恢复它们.所以这是一项具有挑战性的任务.

Technically it is possible, but it would require saving all the system-allocated resources state too - like file descriptors for example and then restoring them. So it's a challenging task.

实现您想要的最简单方法是使用像 VMWare 这样的虚拟机.当你暂停它时，你实际上保存了整个机器状态以及所有正在运行的程序.

The easiest way to achieve what you want is to use a virtual machine like VMWare. When you pause it you actually save the whole machine state together with all programs running.
