< cpp‎ | thread‎ | promise
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 is atomic, i.e. it behaves as though they 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.
