MPI_Win_sync(3)			      MPI		       MPI_Win_sync(3)

NAME
       MPI_Win_sync -  Synchronize public and private copies of	the given win-
       dow.

SYNOPSIS
       int MPI_Win_sync(MPI_Win	win)

       The call	MPI_Win_sync synchronizes the private and public window	copies
       of  win.	 For the purposes of synchronizing the private and public win-
       dow, 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).

INPUT PARAMETERS
       win    -	window object (handle)

THREAD AND INTERRUPT SAFETY
       This routine is thread-safe.  This  means  that	this  routine  may  be
       safely  used by multiple	threads	without	the need for any user-provided
       thread locks.  However, the routine is not interrupt safe.   Typically,
       this  is	due to the use of memory allocation routines such as malloc or
       other non-MPICH runtime routines	that  are  themselves  not  interrupt-
       safe.

NOTES FOR FORTRAN
       All  MPI	routines in Fortran (except for	MPI_WTIME and MPI_WTICK	) have
       an additional argument ierr at the end of the argument list.   ierr  is
       an  integer and has the same meaning as the return value	of the routine
       in C.  In Fortran, MPI routines are subroutines,	and are	 invoked  with
       the call	statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm )	are of type INTEGER in
       Fortran.

ERRORS
       All MPI routines	(except	MPI_Wtime and  MPI_Wtick  )  return  an	 error
       value;  C routines as the value of the function and Fortran routines in
       the last	argument.  Before the value is returned, the current MPI error
       handler	is called.  By default,	this error handler aborts the MPI job.
       The error handler may be	changed	with MPI_Comm_set_errhandler (for com-
       municators),  MPI_File_set_errhandler  (for files), and MPI_Win_set_er-
       rhandler	(for RMA windows).  The	MPI-1 routine  MPI_Errhandler_set  may
       be  used	 but  its  use	is  deprecated.	  The predefined error handler
       MPI_ERRORS_RETURN may be	used to	cause error  values  to	 be  returned.
       Note  that MPI does not guarentee that an MPI program can continue past
       an error; however, MPI implementations will attempt to  continue	 when-
       ever possible.

       MPI_SUCCESS
	      -	No error; MPI routine completed	successfully.
       MPI_ERR_RANK
	      -	 Invalid  source  or  destination rank.	 Ranks must be between
	      zero and the size	of the communicator minus one; ranks in	a  re-
	      ceive  ( MPI_Recv	, MPI_Irecv , MPI_Sendrecv , etc.) may also be
	      MPI_ANY_SOURCE .

       MPI_ERR_WIN
	      -	Invalid	MPI window object
       MPI_ERR_OTHER
	      -	Other error; use  MPI_Error_string  to	get  more  information
	      about this error code.
