MPI_Type_create_hvector(3)

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 routine.

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++ functions 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.
