std::out_ptr_t::~out_ptr_t(3) C++ Standard Libary std::out_ptr_t::~out_ptr_t(3)

NAME

std::out_ptr_t::~out_ptr_t - std::out_ptr_t::~out_ptr_t

Synopsis


~out_ptr_t(); (since C++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.
