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 explicit out_ptr_t( Smart &sp, Args... args ); (1) (since C++23) out_ptr_t( const out_ptr_t& ) = delete; (2) (since C++23) 1) Creates an out_ptr_t. Adapts sp as if binds it to the Smart& mem- ber, captures every argument t in args... as if initializes the corresponding mem- ber of type T in Args... with std::forward<T>(t), then value-initializes the stored Pointer. Then calls sp.reset() if the expression is well-formed; otherwise, calls sp = Smart() if std::is_default_constructible_v<Smart> is true. The pro- gram is ill-formed if both resetting operations are ill-formed. 2) Copy constructor is explicitly deleted. out_ptr_t is neither copyable nor movable. Parameters sp - the object (typically a smart pointer) to adapt args... - the arguments used for resetting to capture Return value (none) Exceptions May throw implementation-defined exceptions. Notes After construction, the Pointer or void* object pointed by the re- turn value of either conversion function is equal to nullptr. Every argument in args... is moved into the created out_ptr_t if it is of an object type, or transferred into the created out_ptr_t as-is if it is of a reference type. The constructor of out_ptr_t is allowed to throw exceptions. For ex- ample, when sp is a std::shared_ptr, the allocation for the new control block may be performed within the constructor rather than the destructor.
