是否保存进程的内存以供以后使用? [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，然后在以后重新加载文件，以便您可以继续执行程序?

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?

修改 我一直在阅读有关此内容的信息:

Edit I've been reading about this:

是否可以转储该结构的内容，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

从技术上讲是可行的，但是它也需要保存所有系统分配的资源状态-例如文件描述符，然后再还原它们.因此，这是一项艰巨的任务.

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.

实现所需目标的最简单方法是使用VMWare等虚拟机.暂停时，实际上可以保存整个计算机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.
