title: input and output without a library in C
body: <p>I'm writing a small kernel for my programs in C.</p>
  
  <p>This is not (at the moment) an OS kernel, it's merely a way for me to keep track of input and output in programs without relying on external source (i.e. stdio.h). You might ask me why I'd ever want to do this; it's just so I know how this works, and so that I have more, and more (end goal is total) control of program flow.</p>
  
  <p>I was wondering if anyone knows some tutorials on input and output in C (with inline asm?) without relying on any other code.</p>
