Member Function Documentation

virtual Status ICounter::Activate ( )

pure virtual

virtual u64 ICounter::Counter ( ) const

pure virtual

Returns: the current value of the counter (all but the lower CounterBits() bits must be zero)

virtual size_t ICounter::CounterBits ( ) const

pure virtual

Returns: the bit width of the counter (<= 64) WHRT uses this to ensure the counter (running at nominal frequency) doesn't overflow more than once during CALIBRATION_INTERVAL_MS.

virtual bool ICounter::IsSafe ( ) const

pure virtual

virtual const char* ICounter::Name ( ) const

pure virtual

virtual double ICounter::NominalFrequency ( ) const

pure virtual

initial measurement of the tick rate.

not necessarily correct (e.g. when using TSC: os_cpu_ClockFrequency isn't exact).
