In this section, we will see how Linux (and a lot of other members of the Unix family) implement common network patterns, and how a user will interact with those while writing networking applications. All discussions in this section will be strictly based on a Linux-like OS with the standard C library (glibc). The Portable OS Interface (POSIX) standard includes all of these, making them portable to any POSIX compliant OS. All functions and data structures here follow C (and C++) coding conventions, but as we will see later, some of these are available in Rust as well through libc bindings.
The most important networking primitive that the OS provides is a socket. Now, what is a socket? A socket is ...
