to the current implementation.

void Get_version(int& version, int& subversion)
- version
- The major version number of the corresponding
standard (integer).
- subversion
- The minor version number of the corresponding
standard (integer).
- IERROR
- Fortran only: Error status (integer).
Since
Open MPI is MPI 2.1 compliant, this function will return a version value
of 2 and a subversion value of 1 for this release.
MPI_Get_version
is one of the few functions that can be called before MPI_Init and after
MPI_Finalize.
Almost all MPI routines return an error value; C routines
as the value of the function and Fortran routines in the last argument.
C++ functions do not return errors. If the default error handler is set
to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI::Exception object.
Before the error value is
returned, the current MPI error handler is called. By default, this error
handler aborts the MPI job, except for I/O function errors. The error handler
may be changed with MPI_Comm_set_errhandler; the predefined error handler
MPI_ERRORS_RETURN may be used to cause error values to be returned. Note
that MPI does not guarantee that an MPI program can continue past an error.
