MPI_Get_version - Returns the version of the standard corresponding to the current implementation.
SYNTAX C Syntax
int MPI_Get_version(int *version, int *subversion)
MPI_GET_VERSION(VERSION, SUBVERSION, IERROR)
INTEGER VERSION, SUBVERSION, IERROR
void Get_version(int& version, int& subversion)
version The major version number of the corresponding standard (integer).
The minor version number of the corresponding standard (integer).
IERROR Fortran only: Error status (integer).
Since Open MPI is MPI 2.0 compliant, this function will return a version value of 2 and a subversion value of 0 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++ func-
tions 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.

NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr
is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked
with the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran routines in
the last argument. Before the value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI
job. The error handler may be changed with MPI_Comm_set_errhandler (for communicators), MPI_File_set_errhandler (for files), and
MPI_Win_set_errhandler (for RMA windows). The MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated. The predefined
error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarentee that an MPI program can
continue past an error; however, MPI implementations will attempt to continue whenever possible.
