This section presents a complete C++ language interface for MPI-/. There are some issues specific to C++ that must be considered in the design of this interface that go beyond the simple description of language bindings. In particular, in C++, we must be concerned with the design of objects and their interfaces, rather than just the design of a language-specific functional interface to MPI-/. Fortunately, the original design of MPI-/ was based on the notion of objects, so a natural set of classes is already part of MPI-/.
Since the original design of MPI-/ did not include a C++ language interface, a complete list of C++ bindings for MPI-/ functions is provided in Annex B. MPI-// includes C++ bindings as part of its function specifications. In some cases, MPI-// provides new names for the C bindings of MPI-/ functions. In this case, the C++ binding matches the new C name -- there is no binding for the deprecated name. As such, the C++ binding for the new name appears in Annex A, not Annex B.
