MPI_Type_create_hvector(3OpenMPI)										 MPI_Type_create_hvector(3OpenMPI)

NAME

       MPI_Type_create_hvector - Creates a vector (strided) data type with offset in bytes.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Type_create_hvector(int count, int blocklength,
	    MPI_Aint stride, MPI_Datatype oldtype, MPI_Datatype *newtype)

Fortran Syntax (see FORTRAN 77 NOTES)
       INCLUDE 'mpif.h'
       MPI_TYPE_CREATE_HVECTOR(COUNT, BLOCKLENGTH, STRIDE, OLDTYPE,
	    NEWTYPE, IERROR)

	    INTEGER   COUNT, BLOCKLENGTH, OLDTYPE, NEWTYPE, IERROR
	    INTEGER(KIND=MPI_ADDRESS_KIND) STRIDE

C++ Syntax
       #include <mpi.h>
       MPI::Datatype MPI::Datatype::Create_hvector(int count,
	    int blocklength, MPI::Aint stride) const

INPUT PARAMETERS

       count	 Number of blocks (nonnegative integer).

       blocklength
		 Number of elements in each block (nonnegative integer).

       stride	 Number of bytes between start of each block (integer).

       oldtype	 Old data type (handle).

OUTPUT PARAMETERS

       newtype	 New data type (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_create_hvector creates a vector (strided) data type with offset in bytes.

       NOTE  -	This  routine replaces MPI_Type_hvector, which is deprecated. See the man page MPI_Type_hvector(3) for information about that rou-
       tine.

FORTRAN 77 NOTES
       The MPI standard prescribes portable Fortran syntax for the STRIDE argument only for Fortran 90.  FORTRAN 77 users may use the non-portable
       syntax

	    INTEGER*MPI_ADDRESS_KIND STRIDE

       where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length of the declared integer in bytes.

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_Type_get_extent - Returns the lower bound and extent of a data type.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Type_get_extent(MPI_Datatype datatype, MPI_Aint *lb,
	    MPI_Aint *extent)

Fortran Syntax (see FORTRAN 77 NOTES)
       INCLUDE 'mpif.h'
       MPI_TYPE_GET_EXTENT(DATATYPE, LB, EXTENT, IERROR)
	    INTEGER   DATATYPE, IERROR
	    INTEGER(KIND=MPI_ADDRESS_KIND) LB, EXTENT

C++ Syntax
       #include <mpi.h>
       void MPI::Datatype::Get_extent(MPI::Aint& lb, MPI::Aint& extent)
	    const

INPUT PARAMETER

       datatype  Data type (handle).

OUTPUT PARAMETERS

       lb	 Lower bound of data type (integer).

       extent	 Data type extent (integer).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_get_extent returns the lower bound and the extent of datatype.

NOTE

       Use of MPI_Type_get_extent is strongly recommended over the old MPI-1 functions MPI_Type_extent and MPI_Type_lb.

FORTRAN 77 NOTES
       The  MPI standard prescribes portable Fortran syntax for the LB and EXTENT arguments only for Fortran 90. FORTRAN 77 users may use the non-
       portable syntax

	    INTEGER*MPI_ADDRESS_KIND LB
       or
	    INTEGER*MPI_ADDRESS_KIND EXTENT

       where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length of the declared integer in bytes.

       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
