13.6. C++ Bindings for Groups, Contexts, and Communicators


Up: MPI-1 C++ Language Binding Next: C++ Bindings for Process Topologies Previous: C++ Bindings for Collective Communication

For both syntactic and semantic reasons, the Dup() functions listed below are not virtual. Syntactically, they must each have a different return type. Dup() and Clone are discussed in Section Communicators .
