303. C++ Classes for MPI


Up: C++ Next: Class Member Functions for MPI Previous: Design

All MPI classes, constants, and functions are declared within the scope of an MPI namespace. Thus, instead of the MPI_ prefix that is used in C and Fortran, MPI functions essentially have an MPI:: prefix.

The members of the MPI namespace are those classes corresponding to objects implicitly used by MPI. An abbreviated definition of the MPI namespace and its member classes is as follows:

Note that there are a small number of derived classes, and that virtual inheritance is not used.
