.. _mpi_win_delete_attr:
MPI_Win_delete_attr
===================
.. include_body
:ref:`MPI_Win_delete_attr` |mdash| Deletes an attribute from a window.
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_Win_delete_attr(MPI_Win win, int win_keyval)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_WIN_DELETE_ATTR(WIN, WIN_KEYVAL, IERROR)
INTEGER WIN, WIN_KEYVAL, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_Win_delete_attr(win, win_keyval, ierror)
TYPE(MPI_Win), INTENT(IN) :: win
INTEGER, INTENT(IN) :: win_keyval
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
INPUT/OUTPUT PARAMETER
----------------------
* ``win``: Window from which the attribute is deleted (handle).
INPUT PARAMETER
---------------
* ``win_keyval``: Key value (integer).
OUTPUT PARAMETER
----------------
* ``ierror``: Fortran only: Error status (integer).
NOTES
-----
Note that it is not defined by the MPI standard what happens if the
delete_fn callback invokes other MPI functions. In Open MPI, it is not
valid for delete_fn callbacks (or any of their children) to add or
delete attributes on the same object on which the delete_fn callback is
being invoked.
ERRORS
------
