Function Documentation

PlatformSpinlockAcquire()

VOID PlatformSpinlockAcquire	(	PKSPIN_LOCK	SpinLock,
		PKIRQL	OldIrql )

Acquire a kernel spinlock, raising IRQL to DISPATCH_LEVEL.

Parameters

SpinLock	Pointer to the KSPIN_LOCK to acquire
OldIrql	Receives the previous IRQL value to be restored on release

Returns

VOID

{
#if defined(_WIN32) || defined(_WIN64)
 
    KeAcquireSpinLock(SpinLock, OldIrql);
 
#elif defined(__linux__)
 
#    error "Not yet implemented"
 
#else
 
#    error "Unsupported platform"
 
#endif
}

PlatformSpinlockInitialize()

VOID PlatformSpinlockInitialize

(

PKSPIN_LOCK

SpinLock

)

Initialize a kernel spinlock.

Parameters

SpinLock

Pointer to the KSPIN_LOCK to initialize

Returns

VOID

{
#if defined(_WIN32) || defined(_WIN64)
 
    KeInitializeSpinLock(SpinLock);
 
#elif defined(__linux__)
 
#    error "Not yet implemented"
 
#else
 
#    error "Unsupported platform"
 
#endif
}

PlatformSpinlockRelease()

VOID PlatformSpinlockRelease	(	PKSPIN_LOCK	SpinLock,
		KIRQL	OldIrql )

Release a previously acquired kernel spinlock and restore IRQL.

Parameters

SpinLock	Pointer to the KSPIN_LOCK to release
OldIrql	The previous IRQL value saved during acquire

Returns

VOID

{
#if defined(_WIN32) || defined(_WIN64)
 
    KeReleaseSpinLock(SpinLock, OldIrql);
 
#elif defined(__linux__)
 
#    error "Not yet implemented"
 
#else
 
#    error "Unsupported platform"
 
#endif
