I was going to teach someone about the kernel, and I wanted to start
them at the system call entry point, but I've forgotten what file that
is located in. I assume it's in the x86-specific code (for the x86
platform, anyway); anyone know offhand?
Also, I recall reading about NT internals versus Unix, and someone
mentioned that if you wanted to add a new system call or change the
meaning of an argument or add an argument, that you got a lot of
resistance in Unix. I'm sure there was a good reason, so why exactly
is that the case? Does NT have a technical advantage in the way it
handles system calls?
