~inout_ptr_t();
Resets the adapted Smart object by the value of modified Pointer object (or the void*
object if operator void**()
has been called) and the captured arguments.
release()
may be called on the adapted Smart object if it is not called by the constructor.

- args... denotes the captured arguments,
- p denotes the value of stored Pointer, or

otherwise, the program is ill-formed.
Notes
The implementation may allocate the storage for the data structure needed for Smart (e.g. a control block) on construction, in order to leave non-throwing works to the destructor.
Arguments captured by value are destroyed after resetting.
