C++ examples with persistent inlet or outlet?

[GoogleCodeExporter]

I'm trying to do something that requires greater knowledge of C++ than I 
currently have.

I am trying to create an Unreal Engine 4 plugin. The engine handles its own 
threading and when to call the Tick functions of each object in the scene. I am 
building a SceneComponent object and I want to use its TickComponent function 
to call inlet.pull_sample. But I don't want to recreate the inlet on every tick 
(75 Hz).

So I thought I'd have the inlet as a member variable in my component class. 
This requires the inlet to be created explicitly upon component instantiation 
because lsl::stream_inlet has no default constructor. I tried constructing it 
with my_inlet(lsl::stream_info("NotAName", "NotAType", 0)), and, though it 
compiles, attempting to add my component to the scene causes a bunch of errors.

So how do I make a placeholder inlet on instantiation? Or is there a better 
solution?

I will try to use the C API instead, but I would really prefer to use the C++ 
API.
