crypto_free_kpp(9)

🎀 NAME 🎀

crypto_free_kpp — bestie, this is the one that frees your KPP tfm handle 💅 (yes, crypto_free_kpp(9), the kernel API manual girlies know)

---

✨ SYNOPSIS ✨

void crypto_free_kpp (struct crypto_kpp *tfm );

okay so it returns void, meaning it gives you nothing back, which is literally the point — it's a cleanup function, she takes and she doesn't give 🫶

---

🌸 ARGUMENTS 🌸

• tfm — the KPP tfm handle, and it has to be one that was allocated with crypto_alloc_kpp 🔥 like, don't just roll up with some random pointer, that's not the vibe

---

💖 DESCRIPTION 💖

So here's the tea ☕: if tfm is a NULL pointer or an error pointer, this function does nothing. not a single thing. zero. she clocks out early 😭

Otherwise it frees the KPP tfm handle for you, no cap. That's the whole plot 🦋
