Retrieve Server Reply before client streams terminates.

[men...@gmail.com]

I can read from documentation:

"A client-streaming RPC is also similar to our simple example, except the client sends a stream of requests to the server instead of a single request. The server sends back a single response, typically but not necessarily after it has received all the client’s requests, along with its status details and optional trailing metadata."

Usually the client does:

    - create channel
    - creaet stub
    - perform the writer = stub->foo(context, reply);
    - loop on:
         writer->Write(request)
    - writer->Done()
    - writer->Finish()
    - At this point I can read the reply


now my question is how can I read the reply before the loop is over? Some time the server indeed stops performing the read loop notifying that there is no need for more requests.
