STRUCT NFT_REGS(9)

💅 struct nft_regs(9) — nf_tables register set

okay so bestie, welcome to the struct nft_regs(9) page from the Kernel API Manual ✨ this is literally the nf_tables register set and it's giving main character energy, so let's get into it 🎀

---

🌸 SYNOPSIS

struct nft_regs {
    union {
      u32 data[NFT_REG32_NUM];
      struct nft_verdict      verdict;
    };
 };

yes the indentation in there is exactly as the kernel gods wrote it, don't come for me 🙈

🦋 Members

• {unnamed_union} — anonymous, no name, no thoughts, just vibes 💅 it's literally an unnamed union and that's iconic of it.
• data — the data registers. that's it, that's the member ✨
• verdict — the verdict register 👑 the one that's special, as you're about to find out.

---

💜 Description

okay so here's the tea 🍓: the first four data registers alias to the verdict register. fr fr. they're sharing the same space, no cap.
