MPI_Win_set_attr(3OpenMPI)                                                        MPI_Win_set_attr(3OpenMPI)



NAME
       MPI_Win_set_attr -SYNTAX MPI_Win_set_attrSYNTAX


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++ 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.
