RxDereferenceAndDeleteRxContext_Real dereferences an RX_CONTEXT data structure and if the ReferenceCount member goes to zero, then it deallocates and removes the specified RX_CONTEXT structure from the RDBSS in-memory data structures.
RxContext [in]A pointer to the RX_CONTEXT structure to be removed.
RxDereferenceAndDeleteRxContext_Real is called by routines other than RxCompleteRequest during asynchronous requests that touch the RxContext parameter in either the initiating thread or in some other thread. Thus, the RX_CONTEXT data structure is reference counted and finalized on the last dereference.
If the ReferenceCount member of the RX_CONTEXT structure pointed to by the RxContext parameter is not zero after being dereferenced (decremented) by the RxDereferenceAndDeleteRxContext_Real routine, then RxDereferenceAndDeleteRxContext_Real causes the system to ASSERT on checked builds.
The RxDereferenceAndDeleteRxContext_Real routine makes a number of specific checks before removing an RX_CONTEXT. These checks include the following:
If the RX_CONTEXT structure was allocated from non-page pool memory (the Flags member of the RX_CONTEXT structure has the RX_CONTEXT_FLAG_FROM_POOL option set), then the RX_CONTEXT structure pointed to by the RxContext parameter will be returned to an internal RDBSS lookaside list or to non-paged pool memory.
