nvme_refresh_topology(2)

💖 nvme_refresh_topology — the libnvme API manual, section 2, bestie 💖

okay so this is a page from the libnvme API manual, section 2, and it's about one tiny little function that does a big job. sit down, grab a strawberry 🍓, let's go.

---

✨ NAME ✨

nvme_refresh_topology — refresh the contents of an nvme_root_t object

like. it's giving "spring cleaning but for your topology" 🧹✨

---

✨ SYNOPSIS ✨

void nvme_refresh_topology (nvme_root_t r );

no return value, no drama, it just... does the thing. main character energy honestly 👑

---

✨ ARGUMENTS ✨

• r — an nvme_root_t object. that's the girlies 💅 this is the thing that's about to get a whole glow-up.

---

✨ DESCRIPTION ✨

so here's the tea 🫖 — nvme_refresh_topology removes all elements in r and then rescans the existing topology.

that's it. that's the whole function.

lowkey iconic, highkey destructive (to the contents of r, not to your actual hardware, bestie, breathe 😭). it wipes the nvme_root_t back to a clean slate and then goes and looks at the topology again from scratch to fill it back in. out with the old, in with the freshly rescanned. periodt. 💅

bestie warning: all the elements in r get removed. every single one. no cap. if you were holding onto anything from that object, it's gone-gone. 🙈
