ice_subscribe_recipe(9)

💖 ice_subscribe_recipe(9) — kernel API manual, but make it make sense 💖

okay so bestie, welcome to ice_subscribe_recipe(9) ✨ this is a kernel API manual page (yes, section 9, the ~spicy~ one) and we're gonna get you subscribed to a recipe that already exists. no cap, that's literally the whole vibe. 🧚

---

✨ NAME ✨

ice_subscribe_recipe — subscribe to an existing recipe 💅

like, the recipe is already out there. you're not cooking a new one. you're just pulling up and saying "yeah, i want in on that one." iconic behavior tbh. 🎀

---

🌸 SYNOPSIS 🌸

int ice_subscribe_recipe (struct ice_hw *hw , u16 rid );

that's it. that's the whole signature. two arguments, one int coming back at you. slay. 💜

---

🦋 ARGUMENTS 🦋

• hw — pointer to the hardware structure. it's giving "here's my whole hardware situation, please be careful with it" 🫶 it's a pointer, so like, it points at the struct ice_hw. that's your context, your main character.
• rid — the recipe ID you wanna subscribe to. a u16, so keep it in range, bestie. this is the specific recipe you're claiming. iykyk. 🔥

---

⭐ RETURN ⭐

0 on success, and others on error.

so, to be crystal clear: 0 = we ate, everything's good 👑. anything that isn't 0 = not 0, i.e. an error of some kind. the page doesn't get more specific than "others," so that's all we're claiming. don't come for me. 💀

ngl, always check your return value. 0 is your bestie, everything else is a vibe check you failed. 🙈

pro tip from me to you: this page is a kernel API page, so it's talking to driver devs, not to your shell. no flags to type, no config to tweak. you're in C territory now, bestie. 💖

and that's the whole thing, bestie!! ✨ this page came from the source tree at ./drivers/net/ethernet/intel/ice, and it's dated October 2026, still signed ice_subscribe_recipe(9) — go be a good kernel citizen and subscribe responsibly. 🎀🦋💜
