MPI_Type_dup(3)

NAME
     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.
