MPI_Type_dup(3OpenMPI)													    MPI_Type_dup(3OpenMPI)

NAME

       MPI_Type_dup - Duplicates a data type with associated key values.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Type_dup(MPI_Datatype type, MPI_Datatype *newtype)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_TYPE_DUP(TYPE, NEWTYPE, IERROR)
	    INTEGER   TYPE, NEWTYPE, IERROR

C++ Syntax
       #include <mpi.h>
       MPI::Datatype MPI::Datatype::Dup() const

INPUT PARAMETER

       type	 Data type (handle).

OUTPUT PARAMETERS

       newtype	 Copy of type (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_dup  is  a  type constructor that duplicates the existing type with associated key values. For each key value, the respective copy
       callback function determines the attribute value associated with this key in the new communicator. One particular action that a copy  call-
       back  may  take	is  to delete the attribute from the new data type. Returns in newtype a new data type with exactly the same properties as
       type, as well as any copied cached information. The new data type has identical upper bound and lower bound and yields the same net  result
       when fully decoded with the functions described in Section 8.6 of the MPI-2 standard. newtype has the same committed state as the old type.

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_get_errhandler	- Retrieves error handler associated with a communicator.

SYNTAX

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

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

C++ Syntax
       #include <mpi.h>
       MPI::Errhandler MPI::Comm::Get_errhandler() const

INPUT PARAMETER

       comm	 Communicator (handle).

OUTPUT PARAMETERS

       errhandler
		 New error handler for communicator (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Comm_get_errhandler retrieves the error handler currently associated with a communicator. This call is identical to MPI_Errhandler_get,
       the use of which is deprecated.

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.
