View the official Windows Driver Kit DDI referenceNo description available.
This macro accesses the type of method as described in the KSMETHOD_ITEM. If the method will be processed asynchronously using KsDispatchSpecificMethod, this storage must be maintained intact.
Irp [in]Specifies the IRP passed to the handler routine.
The relevant 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_TYPE_IRP_STORAGE(Irp) (*(ULONG_PTR*)(&(Irp)->Tail.Overlay.DriverContext[2]))
