The C++ language requires all classes to have four special functions:
a default constructor, a copy constructor, a destructor, and an
assignment operator. The bindings for these functions are listed
below; their semantics are discussed in
Section 10.1.5.
The two constructors are not virtual.
The bindings prototype functions using the type CLASS
rather
than listing each function for every MPI-/ class; the token
CLASS
can be replaced with valid MPI-// class names, such as
Group, Datatype, etc., except when noted.
In addition, bindings are provided for comparison and inter-language
operability from Sections 10.1.5
and 10.1.9.
