Remarks
KSPROPERTY_STREAMALLOCATOR_FUNCTIONTABLE is only used by allocators supporting the DISPATCH_LEVEL function interface. Allocators supporting this property must be able to allocate and free frames for IRQL of DISPATCH_LEVEL and lower. This property is accessible only from kernel mode.
Because the DISPATCH_LEVEL interface is closely associated with the IRP-based interface, acquiring the function table is likely to result in the creation of an internal notification event to allow pending I/O to be completed when frames are returned to the free list. When the handle to the allocator is closed, the function table pointers are invalid and the associated events are automatically disabled.
