[Solved] How to create and restore memory image dump [closed]

Question

This isn’t possible in general. If you tried it, it might fail in subtle and unpredictable ways. Here are a few potential problems:

The process might store its process ID and thread IDs. When you restore it, there is no good way to ensure it gets the same IDs.
The process might have files locked. There’s no way to ensure those files are in the same state.
The process might have files open that no longer exist later. Consider temporary files.
The process might have sockets or pipes open either internally or even to other processes.
The process might have manipulated shared state that communicates with other processes and stopping the process with that shared state in an inconsistent state might disrupt other processes.
The process might have a lock on DLLs or other executable files that may not exist identically when you try to restart the process.

There are a lot of other problems as well. Generally platforms that provide application save/restore capability are either very limited in what they let applications do or they require the close cooperation of the applications.
