NAME

       MPI_Win_set_attr - Sets the value of a window attribute.

SYNTAX


C Syntax

       #include <mpi.h>
       int MPI_Win_set_attr(MPI_Win win, int win_keyval, void *attribute_val)

Fortran Syntax (see FORTRAN 77 NOTES)

       INCLUDE 'mpif.h'
       MPI_WIN_SET_ATTR(WIN, WIN_KEYVAL, ATTRIBUTE_VAL, IERROR)
            INTEGER WIN, WIN_KEYVAL, IERROR
            INTEGER(KIND=MPI_ADDRESS_KIND) ATTRIBUTE_VAL

C++ Syntax

       #include <mpi.h>
       void MPI::Win::Set_attr(int win_keyval, const void* attribute_val)

INPUT/OUTPUT PARAMETER

       win       Window to which attribute will be attached (handle).

INPUT PARAMETERS

       win_keyval
                 Key value (integer).

       attribute_val
                 Attribute value.

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION


FORTRAN 77 NOTES

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

            INTEGER*MPI_ADDRESS_KIND ATTRIBUTE_VAL

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

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++ func-
       tions 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
