[Alfred Persson Forsberg via Phabricator via libc-commits]

alfredfo added a comment.

@sivachandra: Yes, I also wondered about that (re: "Linux implementation does not try to check if stream is actually a file stream"). I don't know what the best solution is. I tried both glibc and llvm-libc with invalid stream as argument and both crashed. Seems like musl libc also just assumes that the file ptr is valid https://elixir.bootlin.com/musl/latest/source/src/stdio/fileno.c#L7
