But that's really just a bit of wishful thinking -- those files/directories don't exist on any mainstream UNIX OS I'm aware of.
- who23 6y agoHey I'm the author. Yes, as far as I know it's just sugar for opening a socket, and there's almost never a file that exists. To treat it as a file, you need to assign a file descriptor to it, which you can then read and write from.
