FltFreePoolAlignedWithTag function (fltkernel.h)

The FltFreePoolAlignedWithTag routine frees a cache-aligned buffer that was allocated by a previous call to FltAllocatePoolAlignedWithTag.


VOID FLTAPI FltFreePoolAlignedWithTag(
  [in] PFLT_INSTANCE Instance,
  [in] PVOID         Buffer,
  [in] ULONG         Tag

Opaque instance pointer for a caller-owned minifilter driver instance that is attached to the volume. Must be the same instance pointer as the one used in the call to FltAllocatePoolAlignedWithTag.

[in] Buffer

Address of the block of pool memory to be freed.

[in] Tag

Tag used to mark the pool block. Must be the same tag as the one used in the call to FltAllocatePoolAlignedWithTag.

Return value



The memory that the Buffer parameter points to must not be accessed after it is freed by FltFreePoolAlignedWithTag.

The caller of FltFreePoolAlignedWithTag can be running at IRQL DISPATCH_LEVEL if a NonPagedXxxPoolType value was specified when the memory was allocated. Otherwise, the caller must be running at IRQL <= APC_LEVEL.
