SYNTAX
------

C Syntax
^^^^^^^^

.. code-block:: c

    int MPI_Cart_get(MPI_Comm comm, int maxdims, int dims[], int
        periods[], int coords[])

Fortran Syntax
^^^^^^^^^^^^^^

.. code-block:: fortran

    USE MPI
    ! or the older form: INCLUDE 'mpif.h'
    MPI_CART_GET(COMM, MAXDIMS, DIMS, PERIODS, COORDS, IERROR)
    	INTEGER COMM, MAXDIMS, DIMS(*), COORDS(*), IERROR
    	LOGICAL PERIODS(*)

Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^

.. code-block:: fortran

    USE mpi_f08
    MPI_Cart_get(comm, maxdims, dims, periods, coords, ierror)
    	TYPE(MPI_Comm), INTENT(IN) :: comm
    	INTEGER, INTENT(IN) :: maxdims
    	INTEGER, INTENT(OUT) :: dims(maxdims), coords(maxdims)
    	LOGICAL, INTENT(OUT) :: periods(maxdims)
    	INTEGER, OPTIONAL, INTENT(OUT) :: ierror
