KeDelayExecutionThread

Hello,

Is there any way to specify 0 (zero) delay in KeDelayExecutionThread() ?

Also, I don’t understand how to use the “Interval” parameter to specify
“absolute” time. Could somebody please explain with an example ?

Currently, I’m doing the following in my code:

delay.LowPart = (ULONG)( - ( 10 * 1000 * 0 ));
delay.HighPart = -1;

And this seems to delay it for approx 54 seconds. Why is this so ?

Thanks
Puja

You must set all the large integer (or LONGLONG).

Negative values means relative time (for eg. -54*1000*1000*10
specify 54 seconds from the time you call some wait) while
positive means absolute time (in UTC of course).

Try to do something like this:

LARGE_INTEGER Delay;

Delay.QuadPart = -1; //0xFFFFFFFFFFFFFFFF
//your variant gets 0xFFFFFFFF00000000
