:ref:`MPI_Win_complete` |mdash| Completes an RMA access epoch on *win* started by
a call to :ref:`MPI_Win_start`


SYNTAX
------


C Syntax
^^^^^^^^

.. code-block:: c

   #include <mpi.h>

   MPI_Win_complete(MPI_Win win)


Fortran Syntax
^^^^^^^^^^^^^^

.. code-block:: fortran

   USE MPI
   ! or the older form: INCLUDE 'mpif.h'
   MPI_WIN_COMPLETE(WIN, IERROR)


Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^

.. code-block:: fortran

   USE mpi_f08
   MPI_Win_complete(win, ierror)
   	TYPE(MPI_Win), INTENT(IN) :: win
   	INTEGER, OPTIONAL, INTENT(OUT) :: ierror


INPUT PARAMETERS
----------------
* ``win``: Window object (handle).

OUTPUT PARAMETERS
-----------------
* ``ierror``: Fortran only: Error status (integer).

DESCRIPTION
-----------

:ref:`MPI_Win_complete` is a one-sided MPI communication synchronization call,
completing an RMA access epoch on *win* started by a call to
:ref:`MPI_Win_start`. :ref:`MPI_Win_complete` enforces the completion of preceding RMA
calls at the origin and not at the target. A put or accumulate call may
not have completed at the target when it has completed at the origin.
