Accessing CPU/RAM usage (like with Task Manager, but via API!)?

Question

Is there a specific way to access \"task manager\" information with the Windows API? I have done a fair bit of searching on the matter, but I can\'t seem to find an API call tha

Answer 1

You can retrieve information about RAM usage with the PSAPI functions, especially EnumProcesses to find all the processes in the system, and GetProcessMemoryInfo to get information about each process' memory usage.

You can retrieve CPU usage for each process with GetProcessTimes. This isn't always perfectly accurate, but I believe the Task Manager produces results that are inaccurate in the same way under the same circumstances.

In case you want it, information about memory usage by the system as a whole is available via GetPerformanceInfo.
