Member Function Documentation

Status CounterTGT::Activate ( )

inlinevirtual

Implements ICounter.

Definition at line 57 of file tgt.cpp.

u64 CounterTGT::Counter ( ) const

inlinevirtual

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

Implements ICounter.

Definition at line 81 of file tgt.cpp.

size_t CounterTGT::CounterBits ( ) const

inlinevirtual

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.

Implements ICounter.

Definition at line 86 of file tgt.cpp.

bool CounterTGT::IsSafe ( ) const

inlinevirtual

Implements ICounter.

Definition at line 72 of file tgt.cpp.

virtual const wchar_t* CounterTGT::Name ( ) const

inlinevirtual

Implements ICounter.

Definition at line 52 of file tgt.cpp.

double CounterTGT::NominalFrequency ( ) const

inlinevirtual

initial measurement of the tick rate.

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

Implements ICounter.

Definition at line 91 of file tgt.cpp.

double CounterTGT::Resolution ( ) const

inlinevirtual

actual resolution [s].

differs from 1/NominalFrequency if the timer adjustment is greater than 1 tick.

Implements ICounter.

Definition at line 96 of file tgt.cpp.

void CounterTGT::Shutdown ( )

inlinevirtual

Implements ICounter.

Definition at line 67 of file tgt.cpp.
