Send RDF Triples to serializer: Raptor RDF Syntax Library Manual

## Send RDF Triples to serializer

Once the serializer has been started, RDF triples can be sent to it via the `raptor_serializer_serialize_statement()` function with a raptor_statement value.

Once all triples are sent, the serializing must be finished with a call to `raptor_serializer_serialize_end()`. In particular, only at this point does the raptor_iostream get flushed or any string constructed for `raptor_serializer_start_to_string()`.

      /* start the serializing somehow */
      while( /* got RDF triples */ ) {
        raptor_serializer_serialize_statement(rdf_serializer, triple);
      }
      raptor_serializer_serialize_end(rdf_serializer);
      /* now can use the serializing result (FILE, string, raptor_iostream) */
