[grpc-io] Re: grpc async stream in C++ client

[julien.torres0 via grpc.io]

Hi Vijay,

Ok, so I changed the code in the following way:
    CompletionQueue cq;
    std::unique_ptr<ClientAsyncReader<Feature> > reader(stub_->
AsyncListFeatures(&context, rect,&cq,(void*)1));
    void* got_tag;
    bool ok;
    bool ret = cq.Next(&got_tag, &ok);
    if (ret && ok && got_tag == (void*)1) {
      while (1) {
        reader->Read(&feature,(void*)1);
        ok = false;
        ret = cq.Next(&got_tag, &ok);
        if (!ret || !ok || got_tag != (void*)1) {
          break;
        }
        std::cout << "Found feature called "
                << feature.name() << " at "
                << feature.location().latitude()/kCoordFactor_ << ", "
                << feature.location().longitude()/kCoordFactor_ << std::endl
;
      }
    }
And now it seems to work properly.
Could you please confirm that it is correct now?

Thanks.

Julien
