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
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.
