💖 libnvme(2) — API Manual 💖

okay bestie, gather round, we're doing libnvme struct lore today and honestly? it's a lil cutie. no cap.

---

✨ NAME ✨

struct nvme_set_feature_event — Set Feature Event Data 🎀

like... it's the struct that carries your Set Feature event data. that's it. that's the vibe. main character energy in four lines of C. 🫶

---

✨ SYNOPSIS ✨

struct nvme_set_feature_event {
    __le32 layout;
    __le32 cdw_mem[0];
 };

ok so it's giving slim. two members, one of them an array of literally zero elements, which is highkey iconic and lowkey unhinged at the same time. we love a flexible-array moment. 💅

---

✨ Members ✨

• layout — Set Feature Event Layout 💖 this is the __le32 that tells you how the whole thing is laid out. it's the blueprint, the mood board, the plan.
• cdw_mem — Command Dwords Memory buffer 🌸 a __le32 buffer of command dwords, declared as cdw_mem[0], which means it hangs off the end of the struct and you keep going for as long as you need. it's the little buffer that could. ✨

fr fr, notice that both of these are __le32, so they're little-endian — don't go swapping byte order on me, bestie, that's not the vibe. 😭

and that's the whole page, babe. short, sweet, ate and left no crumbs. 🍓
