NdisReleaseSpinLock (Windows Embedded CE 6.0)

1/6/2010

This function releases a spin lock that was acquired in a preceding call to the NdisAcquireSpinLock function.

Syntax

VOID NdisReleaseSpinLock(
  PNDIS_SPIN_LOCK SpinLock
);

Parameters

• SpinLock
  [in] Pointer to the acquired spin lock to be released.

Return Value

None.

Remarks

In Windows Embedded CE, NDIS spin locks are implemented using critical sections.

A driver must initialize its spin lock with the NdisAllocateSpinLock function before it calls any other NdisXXXSpinLock function to access the resources protected by that spin lock.

A driver must call the NdisAcquireSpinLock function to acquire the spin lock before it can call this function. Each call to NdisAcquireSpinLock requires a reciprocal call to this function before the driver can call NdisAcquireSpinLock again.

Any spin lock acquired with NdisAcquireSpinLock must be released with this function. Any spin lock acquired with the NdisDprAcquireSpinLock function must be released with the NdisDprReleaseSpinLock function.
