When compiling natively, we have access to a variety of additional modules including the Unix
module. We can interact with directories and files using functions on Unix
.
Here we open the current working directory, grab the first thing out of that directory -- maybe it's a file, maybe it's a directory, maybe it is something else. Lastly, we close the directory.
There are a variety of kinds of files to switch on. Here, we are switching on Regular Files, Directories, Links, and Sockets. Everything else falls through.
