NdisDprReleaseSpinLock (Windows Embedded CE 6.0)

1/6/2010

NdisDprReleaseSpinLock releases a spin lock acquired in the immediately preceding call to NdisDprAcquireSpinLock. Because Windows Embedded CE does not support DPC IRQL, all NdisDprXXX functions perform identically to the non-DPR equivalent.

Syntax

VOID NdisDprReleaseSpinLock(
  PNDIS_SPIN_LOCK SpinLock
);

Parameters

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

Return Value

None.

Remarks

Release of the spin lock allows another driver function to use the resources the lock protects after that function acquires the spin lock.

A spin lock acquired with NdisDprAcquireSpinLock must be released with NdisDprReleaseSpinLock. A spin lock acquired with NdisAcquireSpinLock must be released with NdisReleaseSpinLock.
