HighPerformanceCounter Class Reference
[synsoft.win32.perf]

List of all members.

Detailed Description

A performance counter that uses the high performance hardware counter on the host machine.

This class provides high-resolution performance monitoring using the host machine's high performance hardware counter. This class does not provide meaningful timing information on operating systems that do not provide a high performance hardware counter.


Public Types

typedef long interval_type
 The interval type.

typedef typedef PerformanceCounterScope<
HighPerformanceCounter
> Scope 
scope_type
 The scope type.


Public Methods

void Start ()
 Starts measurement.

void Stop ()
 Ends measurement.

interval_type propget_PeriodCount ()
 The elapsed count in the measurement period.

interval_type propget_Seconds ()
 The number of whole seconds in the measurement period.

interval_type propget_Milliseconds ()
 The number of whole milliseconds in the measurement period.

interval_type propget_Microseconds ()
 The number of whole microseconds in the measurement period.


Member Typedef Documentation

typedef long interval_type
 

The interval type.

The type of the interval measurement, a 64-bit signed integer

typedef typedef PerformanceCounterScope<HighPerformanceCounter> Scope scope_type
 

The scope type.

The type with which instances of the counter class can be subject to the RAII protocol in order to scope particular measurement intervals
