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.
