       • stream: A mongoc_stream_t.

       This  function  shall  flush  any  buffered  bytes in the underlying stream to the physical transport. It
       mimics the API and semantics of fflush(), forcing a write of user space buffered data.

       Not all stream implementations may implement this feature.

       0 is returned on success, otherwise -1 and errno is set.
