After reading about OPEN(2), I am still confused about the returned value.

http://man7.org/linux/man-pages/man2/open.2.html

It says that the returned value is a File Descriptor, but I tried googling it, and cannot find much about file descriptors, and how to use them.

I have a project that requires me to work with file descriptors, and I would like to learn more about their built-in functions.

Can you please provide a examples of working with "fd" after using the OPEN command?
