MPI_Win_set_attr(3)

NAME
     MPI_Win_set_attr - Stores the window attribute value associated with a
     key

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Win_set_attr ( win, win_keyval, attribute_val )
          MPI_Win win;
          int      win_keyval;
          void     *attribute_val;


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER win, win_keyval, ierror
          INTEGER(KIND=MPI_ADDRESS_KIND)  attribute_val

          CALL MPI_WIN_SET_ATTR(win, win_keyval, attribute_val,
          ierror)


STANDARDS
     This function is defined in the MPI-2 standard.

     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Win_set_attr routine stores the window attribute value associated
     with a key.
      This routine accepts the following parameters:

     win            Specifies the window to which the attribute will be
                    attached (handle)

     win_keyval     Specifies the key value, as returned by
                    MPI_Win_create_keyval(3) (integer)

     attribute_val  Specifies the attribute value

     ierror         Specifies the return code value for successful completion,
                    which is in MPI_SUCCESS.  MPI_SUCCESS is defined in the
                    mpif.h file.
NOTES
     The type of the attribute value depends on whether C or Fortran is being
     used.  In C, an attribute value is a pointer (void *).  In Fortran, it is
     a single integer of kind MPI_ADDRESS_KIND.

     If an attribute is already present, the MPI_Win_delete_attr(3) function
     (specified when the corresponding keyval was created) will be called.
