Timer Reference Kernel Interface (Windows Embedded CE 6.0)

1/5/2010

The following table shows the programming elements exported to the kernel from the timer library.

Programming Elements	Description
CurMSec	This global variable indicates the number of milliseconds since boot.
OALTimerIntrHandler	This function implements the timer interrupt handler.
OEMIdle	This function is called by the kernel to place the CPU in the idle state when there are no threads ready to run.
pOEMUpdateRescheduleTime	This function points to the function that reprograms the system timer.
pQueryPerformanceCounter	Optional. This function points to the OEM implementation of the OEMQueryPerformanceCounter function. It should be set for platforms that provide timer functions with higher granularity than GetTickCount.
pQueryPerformanceFrequency	Optional. This function points to the OEM implementation of the OEMQueryPerformanceFrequency function. It should be set for platforms that provide timer functions with higher granularity than GetTickCount.
SC_GetTickCount	This function is called from the OAL and retrieves the number of milliseconds that have elapsed since Windows Embedded CE was started.
