.. _mpi_get_version:
MPI_Get_version
===============
.. include_body
:ref:`MPI_Get_version` |mdash| Returns the version of the standard corresponding
to the current implementation.
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_Get_version(int *version, int *subversion)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_GET_VERSION(VERSION, SUBVERSION, IERROR)
INTEGER VERSION, SUBVERSION, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_Get_version(version, subversion, ierror)
INTEGER, INTENT(OUT) :: version, subversion
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
OUTPUT PARAMETERS
-----------------
* ``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).
DESCRIPTION
-----------
Since Open MPI |ompi_ver| is MPI-|mpi_standard_version| compliant (see
:ref:`this page for more details about Open MPI standards conformance
<release-notes-mpi-standard-conformance-label>`) this function will return a
``version`` value of |mpi_standard_major_version| and a ``subversion``
value of |mpi_standard_minor_version| for this release.
NOTE
----
:ref:`MPI_Get_version` is one of the few functions that can be called
before :ref:`MPI_Init` and after :ref:`MPI_Finalize`.
