Remarks

The CounterInitialize function calls this function; do not call this function directly.

The CTRPP tool includes this function instead of PerfStartProvider if you use the -MemoryRoutines argument or -NotificationCallback argument when calling CTRPP, or if the callback attribute of the provider element is set to "custom".
