如何从OpenProcess（）获取PROCESS_INFORMATION？

Question

In Windows, I can get PROCESS_INFORMATION via CreateProcess(). However, is it possible to get PROCESS_INFORMATION via OpenProcess()?

Answer 1

According to the comments, you are actually interested in enumerating the threads within a process. You can do that using the tool help library. Call CreateToolhelp32Snapshot to create a snapshot of the process. Then enumerate the threads with Thread32First and Thread32Next . MSDN has sample code here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms686852.aspx

This will enumerate the threads in the snapshot, referring to each thread by its ID. You then obtain a handle to a thread, should you need it, by calling OpenThread .
