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.
