int bound_port=0;
std::string server_address("0.0.0.0:50051");
builder.AddListeningPort(server_address,
grpc::SslServerCredentials(ssl_options) &bound_port);
builder.RegisterService(&service);
std::unique_ptr server(builder.BuildAndStart());
if(bound_port == 0) { cout<<"port already in use!" << endl; }
I don't know why above code is not work, the bound_port return always is
50051, I can't get 0 as expected when port already in use.
Thanks for your help in advance!
