WdfSpinLockRelease function (wdfsync.h)
The WdfSpinLockRelease method releases a specified spin lock.
Syntax
void WdfSpinLockRelease(
WDFSPINLOCK SpinLock
);
Parameters
SpinLock
A handle to a framework spin-lock object, obtained by a previous call to WdfSpinLockCreate.
Return value
None
Remarks
A bug check occurs if the driver supplies an invalid object handle.
The WdfSpinLockRelease method releases the spin lock that a driver obtained by previously calling WdfSpinLockAcquire. WdfSpinLockRelease also restores the driver's IRQL to the value that it had before the driver called WdfSpinLockAcquire.
