NAME

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

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Topo_test(MPI_Comm comm, int *top_type)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_TOPO_TEST(COMM, TOP_TYPE, IERROR)
	    INTEGER   COMM, TOP_TYPE, IERROR

C++ Syntax
       #include <mpi.h>
       int Comm::Get_topology() const

INPUT PARAMETER

       comm	 Communicator (handle).

OUTPUT PARAMETERS

       top_type  Topology type of communicator comm (choice).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       The function MPI_Topo_test returns the type of topology that is assigned to a communicator.

       The output value top_type is one of the following:

	   MPI_GRAPH	   graph topology
	   MPI_CART	   Cartesian topology
	   MPI_UNDEFINED   no topology

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception  mechanism
       will be used to throw an MPI:Exception object.

       Before  the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for
       I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN  may	be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.

NAME

       MPI_Comm_set_errhandler	- Attaches a new error handler to a communicator.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Comm_set_errhandler(MPI_Comm comm,
	    MPI_Errhandler errhandler)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_SET_ERRHANDLER(COMM, ERRHANDLER, IERROR)
	    INTEGER   COMM, ERRHANDLER, IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::Comm::Set_errhandler(const MPI::Errhandler& errhandler)

INPUT
/OUTPUT PARAMETER
       comm	 Communicator (handle).

OUTPUT PARAMETERS

       errhandler
		 New error handler for communicator (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Comm_set_errhandler	attaches  a new error handler to a communicator. The error handler must be either a predefined error handler or an
       error handler created by a call to MPI_Comm_create_errhandler. This call is identical to MPI_Errhandler_set, the use  of  which	is  depre-
       cated.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception  mechanism
       will be used to throw an MPI:Exception object.

       Before  the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for
       I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN  may	be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
