That's by far the least interesting usage of RAII and also, annoyingly, the only one the article discusses. The better usage by far is describing ownership. Does a function that takes a pointer take ownership of the pointer? Who knows! It's a mystery! Does a function that takes a std::unique_ptr take ownership of the pointer? You're goddamn right it does. Now do the same with things like file descriptors. Managing FDs in Linux is nightmare difficulty because if you get it wrong there's almost never a crash or segfault to tell you about it. Valgrind won't help you find it. Nothing helps you, you're entirely on your own. In Rust the compiler validates ownership for you, trivially made robust. In C++ you can make a "unique_fd" or similar, and at least make accidental mistakes harder. In C? Idk, apparently according to this article that's just a "many small allocations" and you're just a shitty programmer for doing that (wow, such useful advice lol)
