Oh, I meant getc(), not getchar(), sorry. It looks like read(out ubyte) 
worked on windows.

I'm using ss.readLine() to pull headers from the stream. When the string 
returned from ss.readLine() is empty, then I move on to the stream. I'm 
going to be using this application on Windows, Linux, and Mac, which is 
why I chose D. This feels like I've just entered the newline/carriage 
return nightmare. Should I not be using readLine()? Or is there some 
generic code that will always work and stick me at the beginning of the 
file?
