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.
