NAME

       MPI_Type_hvector - Creates a vector (strided) datatype with offset in bytes -- use of this
       routine is deprecated.

SYNTAX

C Syntax

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

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_TYPE_HVECTOR(COUNT, BLOCKLENGTH, STRIDE, OLDTYPE, NEWTYPE,
                 IERROR)
            INTEGER   COUNT, BLOCKLENGTH, STRIDE, OLDTYPE
            INTEGER   NEWTYPE, IERROR

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 datatype (handle).

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.  Use  MPI_Type_create_hvector
       instead.

       This deprecated routine is not available in C++.

       The function MPI_Type_hvector is identical to MPI_Type_vector, except that stride is given
       in bytes, rather than in elements. The use  for  both  types  of  vector  constructors  is
       illustrated in the examples in Section 3.12.7 of the MPI-1 Standard.

       Assume that oldtype has type map

           {(type(0), disp(0)), ..., (type(n-1), disp(n-1))}

       with  extent ex. Let bl be the blocklength. The newly created datatype has a type map with
       count * bl * n  entries:

         {(type(0), disp(0)), ..., (type(n-1), disp(n-1)),
         (type(0), disp(0) + ex), ..., (type(n-1), disp(n-1) + ex),
         ..., (type(0), disp(0) + (bl -1) * ex),...,(type(n-1),
         disp(n-1) + (bl -1) * ex), (type(0), disp(0) + stride),
         ...,(type(n-1), disp(n-1) + stride), ..., (type(0),
         disp(0) + stride + (bl - 1) * ex), ..., (type(n-1),
         disp(n-1) + stride + (bl -1) * ex), ..., (type(0),
         disp(0) + stride * (count -1)), ...,(type(n-1),
         disp(n-1) + stride * (count -1)), ..., (type(0),
         disp(0) + stride * (count -1) + (bl -1) * ex), ...,
         (type(n-1), disp(n-1) + stride * (count -1) + (bl -1) * ex)}

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.
