DESCRIPTION
       MPITypecreatehvector creates a vector (strided) data type with  off-
       set in bytes.

       NOTE - This routine replaces MPITypehvector, which is deprecated. See
       the man page MPITypehvector(3) for information about that routine.

       The MPI standard prescribes portable  Fortran  syntax  for  the  STRIDE
       argument  only for Fortran 90.  FORTRAN 77 users may use the non-porta-
       ble syntax

            INTEGER*MPIADDRESSKIND STRIDE

       where MPIADDRESSKIND is a constant defined in mpif.h  and  gives  the
       length of the declared integer in bytes.


EERRRROORRSS
       Almost  all MPI routines return an error value; C routines as the value
       of the function and Fortran routines in the last  argument.  C++  func-
       tions  do  not  return  errors.  If the default error handler is set to
       MPI::ERRORSTHROWEXCEPTIONS, 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
       MPICommseterrhandler; the predefined error handler MPIERRORSRETURN
       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.
