NAME
    Flush -- Flushes buffers for a buffered filehandle (V36)

SYNOPSIS
    success = Flush(fh)
    D0              D1

    LONG Flush(BPTR)

FUNCTION
    Flushes any pending buffered writes to the filehandle.  All buffered
    writes will also be flushed on Close().  If the filehandle was being
    used for input, it drops the buffer, and tries to Seek() back to the
    last read position  (so subsequent reads or writes will occur at the
    expected position in the file).

INPUTS
    fh      - Filehandle to flush.

RESULT
    success - Success or failure.

BUGS
    Before V37 release, Flush() returned a random value.  As of V37,
    it always returns success (this will be fixed in some future
    release).
