✨ nvme_scan_topology(2) ✨

okay bestie, welcome to the libnvme API manual 💖 this one's short, sweet, and honestly kind of iconic. let's get into it 🫶

---

🌸 NAME 🌸

nvme_scan_topology — scan the NVMe topology and apply a filter 💅

---

🎀 SYNOPSIS 🎀

int nvme_scan_topology (nvme_root_t r , nvme_scan_filter_t f , void
*f_args );

like... she's giving three arguments and a dream, no cap ✨

---

🦋 ARGUMENTS 🦋

• r — your nvme_root_t object. the whole main-character of the operation, fr fr 👑
• f — the filter you wanna apply. yes queen, decide what you're keeping 🎀
• f_args — a user-specified argument that gets handed off to f. it's literally her little sidekick 💜

---

🌈 DESCRIPTION 🌈

so the way this works: she scans the NVMe topology, then filters out the resulting elements by applying f. that's it. that's the whole vibe check. not me thinking it would be more complicated 😭

---

⭐ RETURN ⭐

• 0 — success. slay, we ate 🍓
• -1 — failure, and errno is set because of course she left a note explaining herself 🙈

lowkey important: if it fails, always check errno, bestie. the error message isn't gonna read itself ✨
