kmsg_dump_rewind(9)

📦 version 7.3.1, in nixpkgs unstable

💫 kmsg_dump_rewind — reset the iterator

okay so real talk bestie, this is a page from the Kernel API Manual (yes, the big scary one, don't panic 🌸) and honestly? It's a tiny little function with main character energy. Let's get into it.

✨ SYNOPSIS ✨

void kmsg_dump_rewind (struct kmsg_dump_iter *iter );

literally one line. one line of pure power. no cap. 👑

🎀 ARGUMENTS 🎀

  • iter — the kmsg dump iterator. that's it, that's the whole arg. it's the little guy getting rewound 🌀

💖 DESCRIPTION 💖

So here's the vibe: this function resets the dumper's iterator. Like, hits the rewind button. back to the start. the way that a cassette tape goes click and suddenly you're at the beginning again 😭

and why do we care?? because once you've rewound it, you can call kmsg_dump_get_line and kmsg_dump_get_buffer again — and use them multiple times within the same dumper.dump callback. yes bestie, multiple times. you're not one-and-done. you get to go again. iconic behavior honestly 🫶

⭐ no cap: if you don't rewind, you don't get a second pass. this tiny function is the whole reason your dumper can loop. give it the respect it deserves 💅
