STRUCT KPP_INSTANCE(9)

✨ struct kpp_instance — KPP template instance ✨

Hiii bestie 💖 welcome to the <struct kpp_instance(9)> page — it's a Kernel API Manual moment, and honestly? iconic. This is where KPP template instances live, and we're gonna walk through every member together, no cap.

🌸 SYNOPSIS 🌸

struct kpp_instance {
    void (*free)(struct kpp_instance *inst);
    union {
      struct {
        char head[offsetof(struct kpp_alg, base)];
        struct crypto_instance base;
      } s;
      struct kpp_alg alg;
    };
 };

🎀 Members 🎀

• free — the callback that gets invoked when the instance gets destroyed (rip little instance 😭). Must be set. Like, non-negotiable bestie — it's required.
• {unnamed_union} — anonymous. That's it, that's the whole vibe. It's an unnamed union, slaying quietly 💅
• s — Internal. This is the generic crypto core instance state, laid out properly so it can alias with alg as needed. Under the hood energy, not for you to poke at 🫶
• alg — the struct kpp_alg implementation that the instance is providing. This is the actual main character of the struct 👑
