Aaaaaah, I see.
As a user application, where i'm standing, they ARE files. I find them
in folders, "ls" shows them, and i have to open them, getting a file
descriptor. "File" for me is the abstraction so named by the unix
designers ("everything is a file, etc.").
I do recognize that there are several types of files, and i can check it
doing "ls -l".
My perspective is from outside, and finishes at the API. And for me that
means that there are files, sockets and pipes, and that's it.
