Socket Question

[John Woolsey]

I was wondering how the socket class is implemented. Does it basically 
assume blocking io? I know you can read without anything there and it 
blocks. Is there a way to hook a callback in so that if data is incoming 
it will do something?

I chased through the lib source code and managed to trace it back to a 
native call. I didn't see anything like a callback there. I just looked 
through a few C/C++ tutorials and don't see anything about callbacks 
there either, but I had to ask.
