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 highperformance_counter	class_type
	This type.
typedef ws_sint64_t	interval_type
	The interval type.
Public Member Functions
void	start ()
	Starts measurement.
void	stop ()
	Ends measurement.
interval_type	get_period_count () const
	The elapsed count in the measurement period.
interval_type	get_seconds () const
	The number of whole seconds in the measurement period.
interval_type	get_milliseconds () const
	The number of whole milliseconds in the measurement period.
interval_type	get_microseconds () const
	The number of whole microseconds in the measurement period.
Static Public Member Functions
Construction
static void	class_init ()
static void	class_uninit ()

void start

(

)

Starts measurement.

Begins the measurement period

void stop

(

)

Ends measurement.

const

The number of whole seconds in the measurement period.

This represents the extent, in whole seconds, of the measurement period

interval_type get_milliseconds

(

)

const

The number of whole milliseconds in the measurement period.

This represents the extent, in whole milliseconds, of the measurement period

interval_type get_microseconds

(

)

const

The number of whole microseconds in the measurement period.

This represents the extent, in whole microseconds, of the measurement period
