用 C 检索 Windows 进程的完整列表 [英] Retrieving a complete list of Windows processes in C

问题描述

我正在为 Windows 开发一个简单的进程统计信息收集库.我正在使用 EnumProcesses() 函数枚举进程，并尝试使用带有 PROCESS_QUERY_INFORMATION 标志的 OpenProcess() 调用打开它们.不过，后者在一堆系统进程中失败了.同时，我看到类似的应用程序(系统内部工具、任务管理器等)似乎能够检索有关这些进程的信息，即使不需要管理员权限.我尝试启用 SeDebugPrivilege 权限，但只有当我以管理员身份运行我的程序时它才有所帮助——而且，我仍然无法打开空闲进程、系统进程和 audiodg 进程(我希望能够检索他们的信息的一致性).

I am developing a simple process statistics collection library for Windows. I'm enumerating the processes with EnumProcesses() function, and I try to open them with OpenProcess() call with PROCESS_QUERY_INFORMATION flag. The latter one fails for a bunch of system processes, though. At the same time, I see that similar applications (sysinternals tools, task manager, etc) seem to be able to retrieve information about these processes even without requiring Administrator privileges. I tried enabling the SeDebugPrivilege privilege, but it did help only when I ran my program as an Administrator -- and still, I could not open the Idle process, the System process and the audiodg process (I would like to be able to retrieve their information for consistency as well).

所以问题是:我怎样才能获得有关所有进程的信息(我看到它是由 3rd 方应用程序完成的，但我不知道是如何完成的)?没有管理员权限是否可以执行此操作?

So the question is: how can I get information about all the processes (I see it done by 3rd-party applications, but I don't see how)? Is it possible to do it without Administrator privileges?
