Abstract (EN): This paper describes CA/C++, Concurrency Annotations in C++, a language extension that regulates method invocations from multiple threads of execution in a shared-memory multiprocessor system. This system provides threads as an orthogonal element to the language, allowing them to travel through more than one object. Statically type-ckecked synchronous and asynchronous method invocations are supported, with return values from asynchronous invocations accessed through first claw future-like objects. Method invocations are regulated with synchronization code defined in a separate class hierarchy, allowing separate definition and inheritance of synchronization mechanisms. Each method is protected by an access flag that can be switched in pre and post-actions, and by a predicate. Both must evaluate to true in order to enable a thread to animate the method code. Flags and method predicates are independently redefinable along the inheritance chain, thus avoiding the inheritance anomaly.
