Detailed Description

A performance counter that provides process-specific performance timings.

This class uses the operating system's performance monitoring facilities to provide timing information pertaining to the calling process only, irrespective of the activities of other processes on the system. This class does not provide meaningful timing information on operating systems that do not provide process-specific monitoring.

Public Types
typedef processtimes_counter	class_type
typedef us_sint64_t	epoch_type
typedef us_sint64_t	interval_type
	The interval type.
Public Member Functions
void	start ()
	Starts measurement.
void	stop ()
	Ends measurement.
interval_type	get_kernel_period_count () const
	The elapsed count in the measurement period for kernel mode activity.
interval_type	get_kernel_seconds () const
	The number of whole seconds in the measurement period for kernel mode activity.
interval_type	get_kernel_milliseconds () const
	The number of whole milliseconds in the measurement period for kernel mode activity.
interval_type	get_kernel_microseconds () const
	The number of whole microseconds in the measurement period for kernel mode activity.
