       • stream: A mongoc_change_stream_t.

       • err: An optional location for a bson_error_t or NULL.

       • reply: A location for a bson_t.

       A boolean indicating if there was an error.

          bool
          mongoc_change_stream_error_document (mongoc_change_stream_t *stream,
                                               bson_error_t *err,
                                               const bson_t **reply);

       Checks if an error has occurred when creating or iterating over a change stream.

       Similar  to  mongoc_cursor_error_document()  if the error has occurred client-side then the reply will be
       set to an empty BSON document. If the error occurred server-side, reply is  set  to  the  server's  reply
       document.
