MPI_File_sync(3)					      MPI_File_sync(3)

NAME
     MPI_File_sync - Causes all previous writes to be transferred to the
     storage device

SYNOPSIS
     C:

	  #include "mpi.h"

	  int MPI_File_sync(MPI_File fh)

     Fortran:

	  INCLUDE "mpif.h" (or USE MPI)

	  INTEGER fh, ierror

	  CALL MPI_FILE_SYNC(fh, ierror)

DESCRIPTION
     MPI_File_sync is a collective operation that causes all previous writes
     to fh by the calling process to be transferred to the storage device.  If
     other processes have made updates to the storage device, all such updates
     become visible to subsequent reads of fh by the calling process.  In
     certain cases, calling MPI_File_sync might be necessary to ensure
     sequential consistency.

     MPI_File_sync accepts the following argument:

     fh	    Specifies the file handle (handle). The user is responsible for
	    ensuring that all nonblocking requests and split collective
	    operations on fh have been completed before calling MPI_File_sync;
	    otherwise, the call to MPI_File_sync is erroneous.

     ierror Specifies the return code value for successful completion, which
	    is in MPI_SUCCESS.	MPI_SUCCESS is defined in the mpif.h file.

   Notes for Fortran
     All MPI objects (for example, MPI_Datatype, MPI_Comm, MPI_File) are of
     type INTEGER.
