NAME
       MPI_Win_wait - Completes an RMA exposure epoch started by a call to MPI_Win_post on win

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

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

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

INPUT PARAMETERS
       win	 Window object (handle).

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

DESCRIPTION
       MPI_Win_wait  is  a one-sided MPI communication synchronization call that completes an RMA exposure epoch started by a call to MPI_Win_post
       on win. This call matches calls to MPI_Win_complete(win) issued by each of the processes that were granted access to the window during this
       epoch.  The  call  to MPI_Win_wait blocks until all matching calls to MPI_Win_complete have occurred. This guarantees that all these origin
       processes have completed their RMA accesses to the local window. When the call returns, all these RMA accesses will have completed  at  the
       target window.

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++ func-
       tions 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.
