This section defines the rules for MPI language binding in general and
for Fortran,
ISO C,
and C++, in particular.
(Note that ANSI C has been replaced by ISO C.)
The C++ language bindings have been deprecated.
Defined here are various object representations,
as well as the naming conventions used for expressing this
standard.
The actual calling sequences are defined elsewhere.
MPI bindings are for Fortran 90, though they are designed
to be usable in Fortran 77 environments.
Since the word PARAMETER is a keyword in the Fortran language, we use
the word ``argument'' to denote the arguments to a subroutine. These
are normally referred to as parameters in C and C++, however, we
expect that C and C++ programmers will understand the word
``argument'' (which has no specific meaning in C/C++), thus allowing
us to avoid unnecessary confusion for Fortran programmers.
Since Fortran is case insensitive, linkers may use either lower case
or upper case when resolving Fortran names. Users of case sensitive
languages should avoid the ``mpi_'' and ``pmpi_'' prefixes.
