NdisStallExecution macro (ndis.h)
The NdisStallExecution function stalls the caller on the current processor for a given interval.
Syntax
void NdisStallExecution(
MicroSecondsToStall
);
Parameters
MicroSecondsToStall
The number of microseconds to delay. A driver should specify no more than 50 microseconds.
Return value
None
Remarks
NdisStallExecution is a processor-dependent function that busy-waits for at least the specified number of microseconds, but not significantly longer.
This function should be called by drivers that must wait for an interval of more than a few instructions but less than 50 microseconds. Drivers that call this routine should minimize the number of microseconds that they specify.
If a driver must wait for an interval longer than 50 microseconds, it should call the NdisMSleep function. Note that callers of NdisMSleep run at IRQL < DISPATCH_LEVEL.
