std::future::share(3) C++ Standard Libary std::future::share(3) NAME std::future::share - std::future::share Synopsis std::shared_future<T> share() noexcept; Transfers the shared state of *this, if any, to a std::shared_future object. Multiple std::shared_future objects may reference the same shared state, which is not possible with std::future. After calling share on a std::future, valid() == false. Parameters (none) Return value A std::shared_future object containing the shared state previously held by *this, if any, constructed as if by std::shared_future<T>(std::move(*this)). Example This section is incomplete Reason: no example Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Correct behavior LWG 2556 C++11 share() requires valid() to be requirement re- moved and made true noexcept See also shared_future waits for a value (possibly referenced by other fu- tures) that is set (C++11) asynchronously (class template) http://cppreference.com 2022.07.31 std::future::share(3)
