Well, yes. The only thing missing is knowing if you have to swap or not, if you don't want to assume your code will run on little endian systems exclusively. Or, on Linux and BSD systems at least, you can use the <endian.h> or <sys/endian.h> functions (https://linux.die.net/man/3/endian https://linux.die.net/man/3/endian) and rely on the libc implementation to do the system/compiler detection for you and use an appropriate compiler builtin inside of an inline function instead of bothering to hack something together in your own code. The article mentions those functions at the bottom, but strangely still recommends hacking up your own macros.
