NAME
       MPI_Win_complete - Completes an RMA access epoch on win started by a
       call to MPI_Win_start


SYNTAX
C Syntax
       #include <mpi.h>
       MPI_Win_complete(MPI_Win win)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_WIN_COMPLETE(WIN, IERROR)


C++ Syntax
       #include <mpi.h>
       void MPI::Win::Complete() const


INPUT PARAMETERS
       win       Window object (handle).


OUTPUT PARAMETERS
       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Win_complete is a one-sided MPI communication synchronization call,
       completing an RMA access epoch on win started by a call to
       MPI_Win_start. 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.



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_Win_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.
