MPI_Type_struct

MPI_Type_struct Creates a struct data type MPI_Type_create_struct.

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Type_struct(int count, int *array_of_blocklengths,
 MPI_Aint *array_of_displacements, MPI_Datatype *array_of_types,
 MPI_Datatype *newtype)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'

MPI_TYPE_STRUCT(COUNT, ARRAY_OF_BLOCKLENGTHS,
     ARRAY_OF_DISPLACEMENTS, ARRAY_OF_TYPES,
     NEWTYPE, IERROR)
 INTEGER COUNT, ARRAY_OF_BLOCKLENGTHS(*)
 INTEGER ARRAY_OF_DISPLACEMENTS(*)
 INTEGER ARRAY_OF_TYPES(*), NEWTYPE, IERROR

INPUT PARAMETERS

  • count: Number of blocks (integer) also number of entries in arrays array_of_types, array_of_displacements, and array_of_blocklengths.
  • array_of_blocklengths: Number of elements in each block (array).
  • array_of_displacements: Byte displacement of each block (array).
  • array_of_types: Type of elements in each block (array of handles to datatype objects).

OUTPUT PARAMETERS

  • newtype: New datatype (handle).
  • ierror: Fortran only: Error status (integer).

DESCRIPTION

Note that use of this routine is deprecated as of MPI-2. For details of use, see MPI_Type_create_struct.
