errno showing 11 or 22 for createChannel(secure and Insecure) and for SayHello

[toran...@gmail.com]

helloworld]# ./greeter_client

Error no 11, error string Resource temporarily unavailableGreeter received: Hello world

helloworld]#

  GreeterClient greeter(grpc::CreateChannel(

      "localhost:50051", grpc::InsecureChannelCredentials()));

  std::string user("world");

  std::string reply = greeter.SayHello(user);

  printf("Error no %d, error string %s", errno, strerror(errno));

  std::cout << "Greeter received: " << reply << std::endl;

Is this expected behavior ?

The message is received. The code you provide didn't show how the "errno" is assigned.

Please refer to https://github.com/grpc/grpc/tree/master/examples/cpp/helloworld to see how to build a gRPC application.

does the grpc create channel or send will set the errno ?
