推荐答案

您想要的是这样的东西...

What you want is something like this...

NTSTATUS hStatus;
SYSTEM_PERFORMANCE_INFORMATION             stSysPerfInfo;

hStatus = NtQuerySystemInformation(SystemPerformanceInformation, &stSysPerfInfo, sizeof(stSysPerfInfo), NULL);
if (hStatus != NO_ERROR)
{
  // Do work....
}

或者看看这个"TaskManager"

Or take a look at this "TaskManager"
