MPI_Topo_test(3)

NAME
     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.
