DESCRIPTION
       Obtains the value of a window 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.
