NAME

       MPI_Type_hindexed  -  Creates an indexed datatype with offsets in bytes
       -- use of this routine is deprecated.

SYNTAX


C Syntax

       #include <mpi.h>
       int MPI_Type_hindexed(int count, int *array_of_blocklengths,
            MPI_Aint *array_of_displacements, MPI_Datatype oldtype,
            MPI_Datatype *newtype)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_TYPE_HINDEXED(COUNT, ARRAY_OF_BLOCKLENGTHS,
                 ARRAY_OF_DISPLACEMENTS, OLDTYPE, NEWTYPE, IERROR)
            INTEGER   COUNT, ARRAY_OF_BLOCKLENGTHS(*)
            INTEGER   ARRAY_OF_DISPLACEMENTS(*), OLDTYPE, NEWTYPE
            INTEGER   IERROR

INPUT PARAMETERS

       count     Number   of   blocks   --   also   number   of   entries   in
                 array_of_displacements  and array_of_blocklengths  (integer).

       array_of_blocklengths
                 Number  of  elements  in  each  block  (array  of nonnegative
                 integers).

       array_of_displacements
                 Byte displacement of each block (array of 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_hindexed instead.

       This deprecated routine is not available in C++.

       The  function  is  identical  to  MPI_Type_indexed,  except  that block
       displacements in array_of_displacements are specified in bytes,  rather
       than in multiples of the oldtype extent.

       Assume that oldtype has type map

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

       with extent ex. Let B be the array_of_blocklength argument and D be the
       array_of_displacements argument. The newly created datatype has
       n x S^count-1
           (i=0)        B[i]  entries:

         {(type(0), disp(0) + D[0]),...,(type(n-1), disp(n-1) + D[0]),...,
         (type(0), disp(0) + (D[0] + B[0]-1)* ex),...,
         type(n-1), disp(n-1) + (D[0]+ B[0]-1)* ex),...,
         (type(0), disp(0) + D[count-1]),...,(type(n-1), disp(n-1) + D[count-1]),...,
         (type(0), disp(0) +  D[count-1] + (B[count-1] -1)* ex),...,
         (type(n-1), disp(n-1) + D[count-1] + (B[count-1] -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.
