inout_ptr_t. Adapts sp as if binds it to the Smart& member, captures every argument t in args... as if initializes the corresponding member of type T in Args... with std::forward<T>(t), then initializes the stored Pointer with sp if Smart is a pointer type, otherwise, initializes it with sp.get(). sp.release() may be called if Smart is not a pointer type, in which case it will not be called again within the destructor.inout_ptr_t is neither copyable nor movable.| sp | - | the object (typically a smart pointer) to adapt |

(none).
May throw implementation-defined exceptions.
If Smart is not a pointer type and sp.release() is not called by the constructor, it may be called by the destructor before resetting sp.
Every argument in args... is moved into the created inout_ptr_t if it is of an object type, or transferred into the created inout_ptr_t as-is if it is of a reference type.
The constructor of inout_ptr_t is allowed to throw exceptions. For example, when sp is an intrusive pointer with a control block, the allocation for the new control block may be performed within the constructor rather than the destructor.
