DESCRIPTION
       For  the  given  data type, MPITypesetattr sets the key value to the
       value of the specified attribute.


FFOORRTTRRAANN 7777 NNOOTTEESS
       The  MPI  standard  prescribes  portable   Fortran   syntax   for   the
       ATTRIBUTEVAL  argument  only  for Fortran 90. FORTRAN 77 users may use
       the non-portable syntax

            INTEGER*MPIADDRESSKIND ATTRIBUTEVAL

       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.
