nvme_subsys...each_ns_safe(2)

✨ NAME ✨

nvme_subsystem_for_each_ns_safe — the little macro bestie that walks you through your namespaces 🦋 safely, no cap

This one lives in the libnvme API manual, section 2, so you know it's a real one 💅

---

🎀 SYNOPSIS 🎀

nvme_subsystem_for_each_ns_safe (s , n , _n );

like... that's it. that's the whole vibe. three lil things go in, namespaces come out ✨

---

💖 ARGUMENTS 💖

• s — an nvme_subsystem_t object. the main character 👑 the subsystem you're iterating over.
• n — an nvme_ns_t object. this is your namespace, the one you're looking at right now, one at a time 🌸
• _n — a nvme_ns_t_node to use as temporary storage. ikykyk — it's the scratch space so the loop can keep its footing and not eat itself. literally the seatbelt of this whole operation 🫶

heads up bestie: _n is doing real work behind the scenes, so don't go touching it or reusing it for something cute. it's temp storage, that's its whole job, periodt 💀

🌈 A LIL NOTE ON THE NAME 🌈

notice the _safe at the end? that's the whole point, fr fr — it's the "plain" variant's glow-up so you can bail out mid-loop without the iterator tripping over itself. very demure, very mindful, very safe 🎀

that's the whole page, gorgeous 🌟 nothing hidden, nothing skipped.
