Well, at the end of the day macos is in fact a BSD based system ;) About memory safety, if we know the buffer has enough memory, it’s okay. I completely agree with Branko. I believe in that snippet of code, the function is used to format a number which realistically could never exceed like 16 bytes. I wouldn’t say you should avoid a specific function just because you don’t like it or somebody on the internet says so. It’s fine whenever you know what you’re doing. Then, some day it leads to Rust rewrites… >
