NAME
       MPI_File_sync - Makes semantics consistent for data-access operations (collective).

SYNTAX
       C Syntax
	   #include <mpi.h>
	   int MPI_File_sync(MPI_File fh)

       Fortran Syntax
	   INCLUDE 'mpif.h'
	   MPI_FILE_SYNC(FH, IERROR)
		  INTEGER    FH, IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::File::Sync()

INPUT PARAMETER
       fh	 File handle (handle).

OUTPUT PARAMETER
       IERROR	 Fortran only: Error status (integer).

DESCRIPTION
       Calling	MPI_File_sync  with  fh  causes all previous writes to fh by the calling process to be written to permanent storage. If other pro-
       cesses have made updates to permanent storage, then all such updates become visible to subsequent reads of fh by the calling process.

       MPI_File_sync is a collective operation. The user is responsible for ensuring that all nonblocking  requests  on  fh  have  been  completed
       before calling MPI_File_sync. Otherwise, the call to MPI_File_sync is erroneous.

ERRORS
       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception  mechanism
       will be used to throw an MPI:Exception object.

       Before  the error value is returned, the current MPI error handler is called. For MPI I/O function errors, the default error handler is set
       to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL  may
       be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
