       version   The major version number of the corresponding standard (inte-

                 The minor version number of the corresponding standard (inte-

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       Since Open MPI is MPI 2.0 compliant, this function will return  a  ver-
       sion value of 2 and a subversion value of 0 for this release.


NNOOTTEE
       MPIGetversion  is  one of the few functions that can be called before
       MPIInit and after MPIFinalize.


EERRRROORRSS
       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::ERRORSTHROWEXCEPTIONS, 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
       MPICommseterrhandler; the predefined error handler MPIERRORSRETURN
       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.
