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

Member Function Documentation

interval_type propget_Microseconds (    )  [inline]

The number of whole microseconds in the measurement period. This represents the extent, in whole microseconds, of the measurement period

interval_type propget_Milliseconds (    )  [inline]

The number of whole milliseconds in the measurement period. This represents the extent, in whole milliseconds, of the measurement period

interval_type propget_PeriodCount (    )  [inline]

The elapsed count in the measurement period. This represents the extent, in machine-specific increments, of the measurement period

interval_type propget_Seconds (    )  [inline]

The number of whole seconds in the measurement period. This represents the extent, in whole seconds, of the measurement period

void Start (    )  [inline]

Starts measurement. Begins the measurement period

void Stop (    )  [inline]

Ends measurement. Ends the measurement period
