MPI_Graph_get - Retrieves graph topology information
       associated with a communicator


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Graph_get ( comm, maxindex, maxedges,
            index, edges )
            MPI_Comm comm;
            int maxindex, maxedges;
            int *index, *edges;

       C++:

            #include <mpi.h>

            void Graphcomm::Get_topo(
            int               maxindex,
            int               maxedges,
            int               index[],
            int               edges[]) const

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER comm, maxindex, maxedges, index(*), edges(*), ierror

            CALL MPI_GRAPH_GET(comm, maxindex, maxedges, index(*), edges(*), ierror)


STANDARDS

       This release implements the MPI 1.2 standard, as
       documented by the MPI Forum in the spring 1997 release of
       MPI:  A Message Passing Interface Standard.


DESCRIPTION

       The MPI_Graph_get routine retrieves graph topology
       information associated with a communicator.  This routine
       accepts the following parameters:

       comm           Specifies the communicator with a graph
                      structure (handle)

       maxindex       Specifies the length of the vector index in
                      the calling program (integer)

       maxedges       Specifies the length of the vector edges in
                      the calling program (integer)

                      graph structure for node degrees (for
                      details, see MPI_Graph_create(3))

       edges          Returns an array of integers containing the
                      graph structure for graph edges (for
                      details, see MPI_Graph_create(3))

       ierror         Specifies the return code value for
                      successful completion, which is in
                      MPI_SUCCESS.  MPI_SUCCESS is defined in the
                      mpif.h file.
