MPI_Type_dup - Duplicates an MPI datatype


SYNOPSIS

       #include <mpi.h>

       int MPI_Type_dup( type, newtype )

       MPI_Datatype        type;

       MPI_Datatype        *newtype;


STANDARDS

       This function is defined in the MPI-2 standard.

       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_Type_dup routine duplicates an existing MPI data
       type.  The new datatype newtype is returned with the same
       properties as type.  newtype has the same committed state
       as type.

       MPI_Type_dup accepts the following arguments:

       type        The datatype being copied.

       newtype     The duplicate datatype created.


NOTES

       All MPI routines in Fortran (except for MPI_Wtime(3) and
       MPI_Wtick(3)) have an additional ierr argument at the end
       of the argument list.  ierr is an integer and has the same
       meaning as the return value of the routine in C.  In
       Fortran, MPI routines are subroutines and are invoked with
       the CALL statement.  Additionally, in Fortran, all MPI
       objects (for example, MPI_Datatype and MPI_Comm) are of
       type integer.
