NAME

       MPI_Win_sync, - Synchronize the private and public copies of the window

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Win_sync (MPI_Win win)

Fortran Syntax

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

Fortran 2008 Syntax

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

INPUT PARAMETERS

       win       Window object (handle).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Win_sync synchronizes the private and public window copies of win. For the purposes of
       synchronizing the private and public window, MPI_Win_sync has the  effect  of  ending  and
       reopening  an  access and exposure epoch on the window (note that it does not actually end
       an epoch or complete any pending MPI RMA operations).

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and
       Fortran routines in the last argument.

       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_Comm_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.
