This function delays execution of the caller for a specified interval, in microseconds.

VOID
NdisMSleep(
IN ULONG
MicrosecondsToSleep
);

Parameters

MicrosecondsToSleep

Specifies the number of microseconds to delay.

Remarks

For the specified MicrosecondsToSleep, the caller's thread of execution is put into a wait state, thus allowing other threads to get work done on the current processor. When the specified interval expires, the caller of this function resumes execution.

An NDIS driver should always call this function in preference to the NdisStallExecutionfunction. This function can accept a larger delay interval than NdisStallExecution, which should never be called with an interval greater than 50 microseconds.

Network adapter drivers can call this function from their MiniportInitializeand, possibly, MiniportHaltfunctions when either function must wait for state changes to occur in the network adapter before that function continues its operations.

Both this function and NdisStallExecutionallow a network adapter driver to specify a delay consistently and independently of the clock speed of the host CPU. Neither function involves a timer object used by the NdisMSetTimeror the NdisMSetPeriodicTimerfunction. The resolution of the host system clock varies, so very short delays can take slightly longer than the caller of this function or NdisStallExecutionspecified.
