nla_for_each_nested(9)

🌸 nla_for_each_nested(9) 🌸

okay bestie, welcome to the Kernel API Manual ✨ this little gem lives in nla_for_each_nested(9) and honestly? it's giving "tiny macro, big responsibilities" 💅

---

💖 NAME 💖

nla_for_each_nested — iterate over nested attributes 🎀

like, literally just loop through the nested attrs, no cap.

---

✨ SYNOPSIS ✨

nla_for_each_nested (pos , nla , rem );

yes that's the whole thing, she's compact 🫶 (those spaces are exactly how she's written, don't come for her)

---

🦋 ARGUMENTS 🦋

• pos — the loop counter 🌀 — it gets set to the current attribute, so like, that's your "where am I right now" girlie
• nla — the attribute containing the nested attributes 🎁 — the momma attribute, iykyk
• rem — initialized to len, holds bytes currently remaining in stream 📏 — your little remaining-bytes tracker, keep an eye on her
