Detailed Description

Measure CPU time spent executing instructions of this thread.

ThreadUserTimer requires support of the OS. On Unix-based it reports process time. On Windows NT or later desktops and servers it reports thread times with performance counter precision.. On Windows Phone and Windows Store it reports wall clock time with performance counter precision. On all others it reports wall clock time.

Note: ThreadUserTimer only works correctly on Windows NT or later desktops and servers.

Member Function Documentation

◆ GetCurrentTimerValue()

TimerWord ThreadUserTimer::GetCurrentTimerValue ( )

virtual

Retrieve the current timer value.

Returns: the current timer value

Implements TimerBase.

Definition at line 121 of file hrtimer.cpp.

◆ TicksPerSecond()

TimerWord ThreadUserTimer::TicksPerSecond ( )

virtual

Retrieve ticks per second.

Returns: ticks per second

TicksPerSecond() is not the timer resolution. It is a conversion factor into seconds.

Implements TimerBase.
