The semantics of the member functions constituting the C++ language
binding for MPI-/ are specified by the MPI-/ function description
itself. Here, we specify the semantics for those portions of the C++
language interface that are not part of the language binding.
In this subsection, functions are prototyped using the type
MPI::CLASS
rather than listing each function
for every MPI-/ class; the word
CLASS
can be
replaced with any valid MPI-/ class name (e.g., Group),
except as noted.
