MPI_TYPE_DUP(3)MPI_TYPE_DUP(3)NAMEMPI_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.
