In plain C, this is not possible, but since the question is also tagged “Windows”:
CPU usage is CPU time divided by real time. The GetThreadTimes and GetProcessTimes functions give you that information (among other features such as performance counters, which Joachim Pileborg mentioned above, but I think this one is probably easier).
You probably also want to use CreateToolhelp32Snapshot first to know what processes and threads exist at all. You’ll need to translate thread/process IDs to handles, but I guess that won’t be a big hurdle (i.e.
OpenProcess).
