std::promis...thread_exit(3) C++ Standard Libary std::promis...thread_exit(3) NAME std::promise::set_exception_at_thread_exit - std::promise::set_excep- tion_at_thread_exit Synopsis void set_exception_at_thread_exit( std::exception_ptr p ); (since C++11) Stores the exception pointer p into the shared state without making the state ready immediately. The state is made ready when the current thread exits, after all variables with thread-local storage duration have been destroyed. The operation behaves as though set_value, set_exception, set_value_at_thread_exit, and set_exception_at_thread_exit acquire a single mutex associated with the promise object while updating the promise object. An exception is thrown if there is no shared state or the shared state already stores a value or exception. Calls to this function do not introduce data races with calls to get_future (therefore they need not synchronize with each other). Parameters p - exception pointer to store. The behavior is undefined if p is nullptr. Return value (none) Exceptions std::future_error on the following conditions: * *this has no shared state. The error code is set to no_state. * The shared state already stores a value or exception. The error code is set to promise_already_satisfied. Example This section is incomplete Reason: no example See also set_exception sets the result to indicate an exception (public member function) http://cppreference.com 2022.07.31 std::promis...thread_exit(3)
