This macro accesses a pointer to the relevant KSMETHOD_ITEM. Note that this pointer is only set when using KsMethodHandlerWithAllocator.
Irp [in]Specifies the IRP passed to the handler routine.
The pointer to a KSMETHOD_ITEM structure is extracted from Irp->Tail.Overlay.DriverContext. Parameters in DriverContext are initialized by KsMethodHandler and KsMethodHandlerWithAllocator.
The macro is defined as follows:
#define KSMETHOD_ITEM_IRP_STORAGE(Irp) (*(const KSMETHOD_ITEM**)&(Irp)->;Tail.Overlay.DriverContext[3])
