ftrace_rec_iter_record(9)

💅 ftrace_rec_iter_record — like, the Kernel API Manual, bestie ✨

okay so real talk, this one is from the ftrace_rec_iter_record(9) page in the Kernel API Manual, and it is so niche but honestly kind of iconic once you get it. grab a strawberry 🍓 and let's go.

---

🌸 NAME 🌸

ftrace_rec_iter_record — literally just get the record at the iterator location. that's it. that's the whole vibe. 💖

---

✨ SYNOPSIS ✨

struct dyn_ftrace * ftrace_rec_iter_record (struct ftrace_rec_iter *iter );

like yes, it returns a struct dyn_ftrace * and it takes one arg. no cap. 🫶

---

🎀 ARGUMENTS 🎀

• iter — the current iterator location. that's your spot in the iteration, bestie, you're standing right there 💅

---

🌈 RETURN 🌈

it hands you back the record that the current iter is at. that's the whole deal, no plot twist. 👑
