SYNTAX
------

C Syntax
^^^^^^^^

.. code-block:: c

    int MPI_Dist_graph_create(MPI_Comm comm_old, int n, const int
        sources[], const int degrees[], const int destinations[], const
        int weights[], MPI_Info info, int reorder, MPI_Comm*
        comm_dist_graph)

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

.. code-block:: fortran

    USE MPI
    ! or the older form: INCLUDE 'mpif.h'
    MPI_DIST_GRAPH_CREATE(COMM_OLD, N, SOURCES, DEGREES, DESTINATIONS, WEIGHTS, INFO, REORDER, COMM_DIST_GRAPH, IERROR)
    	INTEGER COMM_OLD, N, SOURCES(*), DEGREES(*), DESTINATIONS(*), WEIGHTS(*), INFO, COMM_DIST_GRAPH, IERROR
    	LOGICAL REORDER

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

.. code-block:: fortran

    USE mpi_f08
    MPI_Dist_graph_create(comm_old, n, sources, degrees, destinations, weights, info, reorder, comm_dist_graph, ierror)
    	TYPE(MPI_Comm), INTENT(IN) :: comm_old
    	INTEGER, INTENT(IN) :: n, sources(n), degrees(n), destinations(*), weights(*)
    	TYPE(MPI_Info), INTENT(IN) :: info
    	LOGICAL, INTENT(IN) :: reorder
    	TYPE(MPI_Comm), INTENT(OUT) :: comm_dist_graph
    	INTEGER, OPTIONAL, INTENT(OUT) :: ierror
