 (since 哋它亢++23)

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.

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.

If s.reset(static_cast<SP>(p), std::forward<Args>(args)...) is well-formed, the destructor performs

if (p) 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) s = Smart(static_cast<SP>(p), std::forward<Args>(args)...);,

otherwise, the program is ill-formed.

Notes

If Smart is a std::shared_ptr specialization, the implementation may allocate the storage for the new control block on construction, in order to leave non-throwing works to the destructor.

Arguments captured by value are destroyed after resetting.
