CPU monitoring

Does anyone know how to monitor the cpu usage of a process or thread? I think it has something to do with certain entries in the registry being modified by the system in real time, but I couldn't find those entries on my computer.

Forget the registry!

Take a look at this function:

Code:

BOOL GetProcessTimes(
  HANDLE hProcess,           // handle to process
  LPFILETIME lpCreationTime, // process creation time
  LPFILETIME lpExitTime,     // process exit time
  LPFILETIME lpKernelTime,   // process kernel-mode time
  LPFILETIME lpUserTime      // process user-mode time
);

If you want other processs information, perhaps these functions are of interest:

Code:

BOOL GetProcessIoCounters(
  HANDLE hProcess,           // handle to process
  PIO_COUNTERS lpIoCounters  // I/O accouting information
);

BOOL GetProcessMemoryInfo(
  HANDLE Process,                          // handle to process
  PPROCESS_MEMORY_COUNTERS ppsmemCounters, // buffer
  DWORD cb                                 // size of buffer
);
