Flag a parameter of a smart pointer kind (a kind that overloads operator-> or operator*) that may be copyable/movable but in no way copied/moved from while in the operate human body, and that's by no means modified, and that's not passed together to a different functionality that can achieve this.

This segment appears to be like why not look here at passing messages in order that a programmer doesn’t really need to do express synchronization.

// low cost: one increment handles this entire function and all the decision trees under us vehicle pin = g_p; // Fantastic: passing pointer or reference obtained from a local unaliased clever pointer f(*pin); // Great: same reason pin->func();

???? should there certainly be a “use X instead of std::async” the place X is something that would use a far better specified thread pool?

A class with any virtual operate mustn't Have got a copy constructor or duplicate assignment operator (compiler-produced or handwritten).
