Utilizing a synchronized_value makes sure that the information features a mutex, and the best mutex is locked when the data is right here accessed.

Flag a parameter of a smart pointer type (a type that overloads operator-> or operator*) that is copyable/movable but under no circumstances copied/moved from in the perform entire wikipedia reference body, and that's hardly ever modified, and that is not handed along to another function that may do this. Meaning the possession semantics usually are not used.
