GetIdleTime (Compact 2013)

3/28/2014

This function returns the amount of time, in milliseconds, that the master processor has been idle.

Syntax

DWORD GetIdleTime (void);

Parameters

None.

Return Value

The number of milliseconds that the master processor has been idle. If GetIdleTime returns MAXDWORD, your platform does not support this functionality.

Remarks

To get the idle time for processors other than the master in a Symmetric Multiprocessing (SMP) environment, use CeGetIdleTimeEx. The following two function calls are equivalent:

dwIdleTime = GetIdleTime();
CeGetIdleTimeEx (1, &dwIdleTime);

Example

The following example code shows how to determine how long the master processor has been idle by wrapping a call to GetIdleTime with calls to GetTickCount.

dwStartTick = GetTickCount();
dwIdleSt = GetIdleTime();
//  You must insert a call to the Sleep(sleep_time) function to allow
//  idle time to accrue. An example of an appropriate sleep time is
//  1000 ms.
sleep(1000);
dwStopTick = GetTickCount();
dwIdleEd = GetIdleTime();
PercentIdle = ((100*(dwIdleEd - dwIdleSt)) / (dwStopTick - dwStartTick));
