crypto_spawn_kpp_alg(9)

💜 crypto_spawn_kpp_alg — bestie edition

okay so this is a page from the Kernel API Manual, and honestly? it's a little one but it matters, so let's get into it 🫶

---

✨ NAME ✨

crypto_spawn_kpp_alg — get the algorithm a KPP spawn has been bound to. that's the whole vibe. you hand it a spawn, it hands you back the alg. slay 💅

---

🌸 SYNOPSIS 🌸

struct kpp_alg * crypto_spawn_kpp_alg (struct crypto_kpp_spawn *spawn );

literally one argument, one return, no drama ✨

---

🎀 ARGUMENTS 🎀

• spawn — the spawn you want the referenced struct kpp_alg for. that's it, that's the input 🦋

---

🔥 DESCRIPTION 🔥

so here's the thing bestie, and i need you to actually listen to this part because it's giving timing 👑

this function — and the result it gives you — are safe to use only in this very specific window:

• after spawn has been successfully bound via crypto_grab_kpp, and
• up to until the template instance owning spawn has either been registered successfully, or the spawn has been released again via crypto_drop_spawn.

that's the window. before it? nope. after it? also nope 🙈 use it outside that window and you're on your own, no cap.

---

⭐ RETURN ⭐

a pointer to the struct kpp_alg referenced from the spawn. one pointer, zero surprises 💖
