Description

The WdfSpinLockAcquire method acquires a specified spin lock.

Parameters

`SpinLock`

A handle to a framework spin-lock object, obtained by a previous call to WdfSpinLockCreate.

Remarks

The WdfSpinLockAcquire method returns after the specified spin lock has been acquired. For KMDF, the method returns at IRQL = DISPATCH_LEVEL. For UMDF, the method returns at passive. Your driver cannot call WdfSpinLockAcquire to acquire a spin lock that the driver has specified in a WDF_INTERRUPT_CONFIG structure. For more information about spin locks, see Using Framework Locks.
