devl_traps_register(9)

💅 devl_traps_register(9) 🎀

okay bestie, so this is a page straight out of the Kernel API Manual — yes, that manual — and it's all about one little function that makes your packet traps show up in devlink. no cap, it's a short one, so let's get into it ✨

---

✨ NAME ✨

devl_traps_register — register packet traps with devlink. that's the whole vibe. you've got traps, you want them registered, this is the girl for the job 💖

---

🌸 SYNOPSIS 🌸

int devl_traps_register (struct devlink *devlink , const struct
       devlink_trap *traps , size_t traps_count , void *priv );

look at her. four arguments, one int coming back at you. iconic 💅

---

🦋 ARGUMENTS 🦋

• devlink — the devlink. yeah, THE devlink. your devlink. the one you're registering these traps with 🫶
• traps — packet traps. the actual traps themselves, plural, because one trap is never the whole story ✨
• traps_count — count of provided packet traps. how many of them you're handing over. size_t, so it's a big-girl number 🔥
• priv — driver private information. your stuff, your data, nobody else's business 🙈

---

⭐ RETURN ⭐

Non-zero value on failure. that's it, that's the whole deal — if it comes back zero you're slaying, if it comes back non-zero something went sideways 💀
