MPI_Type_create_hvector(3)         Open MPI         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.
