MPI_Topo_test - Determines the type of topology (if any)
       associated with a communicator


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Topo_test ( comm, top_type )
            MPI_Comm  comm;
            int      *top_type;

       C++:

            #include <mpi.h>

            int Comm::Get_topo()

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER comm, status, ierror,

            CALL MPI_TOPO_TEST(comm, status, 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_Topo_test routine determines the type of topology
       (if any) associated with a communicator.  This routine
       accepts the following parameters:

       comm      Specifies the communicator (handle)

       top_type  Returns the topology type of communicator comm
                 (choice)

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