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.
