static __declspec ( align(64)  )

static Status ActivateCounter ( ICounter *  counter )

inlinestatic

static u64 Counter ( )

inlinestatic

static u64 CounterDelta ( u64  oldCounter, u64  newCounter  )

inlinestatic

Returns

difference [ticks], taking rollover into account. (time-critical, so it's not called through ICounter.)

static ICounter* GetNextBestSafeCounter ( )

static

Returns

the newly created and unique instance of the next best counter that is deemed safe, or 0 if all have already been created.
