1/5/2010
The following table shows the programming elements exported to the kernel from the timer library.
| Programming Elements | Description |
|---|---|
This global variable indicates the number of milliseconds since boot. |
|
This function implements the timer interrupt handler. |
|
This function is called by the kernel to place the CPU in the idle state when there are no threads ready to run. |
|
This function points to the function that reprograms the system timer. |
|
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. |
|
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. |
|
This function is called from the OAL and retrieves the number of milliseconds that have elapsed since Windows Embedded CE was started. |
