std::inout_ptr_t<Smart,Pointer,Args...>::~inout_ptr_t

~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.

Let.

• s denotes the adapted Smart object,
• args... denotes the captured arguments,
• p denotes the value of stored Pointer, or static_cast<Pointer>(*operator void**()) if operator void** has been called,
• SP be
  • Smart::pointer, if it is valid and denotes a type, otherwise,
  • Smart::element_type*, if Smart::element_type is valid and denotes a type, otherwise,
  • std::pointer_traits<Smart>::element_type*, if std::pointer_traits<Smart>::element_type is valid and denotes a type, otherwise,
  • Pointer,
• /*do-release*/ denotes s.release() if the constructor does not call release(), empty otherwise.

If Smart is a pointer type, the destructor performs if (p) s = static_cast<Smart>(p);, and the program is ill-formed if sizeof...(Args) > 0,

otherwise, if s.reset(static_cast<SP>(p), std::forward<Args>(args)...) is well-formed, the destructor performs if (p) { /*do-release*/; s.reset(static_cast<SP>(p), std::forward<Args>(args)...); },

otherwise, if std::is_constructible_v<Smart, SP, Args...> is true, the destructor performs if (p) { /*do-release*/; s = Smart(static_cast<SP>(p), std::forward<Args>(args)...); },

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.
