MPI_GRAPH_GET(3)					      MPI_GRAPH_GET(3)

NAME
     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)

     index	    Returns an array of integers containing the 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.
