nvme_ctrl_config_match(2)

💖 nvme_ctrl_config_match — a lil love letter from the libnvme API manual 💖

okay so bestie, welcome to the nvme_ctrl_config_match(2) page, part of the libnvme API manual. buckle up, it's a short one but it's iconic 🌟

---

✨ NAME ✨

nvme_ctrl_config_match — Check if ctrl @c matches config params 💅

---

🌸 SYNOPSIS 🌸

bool nvme_ctrl_config_match (struct nvme_ctrl *c , const char *transport , const char *traddr , const char *trsvcid , const char *subsysnqn , const char *host_traddr , const char *host_iface );

no cap, that's the whole signature. she's giving "small function, big responsibility" 👑

---

🎀 ARGUMENTS 🎀

• c — an existing controller instance. it's real, it's already out here living its life 🦋
• transport — transport name, like, the vibe of how we're moving 🚚
• traddr — transport address. where she at, literally 📍
• trsvcid — transport service identifier 🔑
• subsysnqn — subsystem NQN. yes, the whole NQN, not a nickname 🙈
• host_traddr — host transport address 🏠
• host_iface — host interface name 🌈

---

💜 DESCRIPTION 💜

so here's the tea ☕ — this function checks that controller c matches these parameters: transport, traddr, trsvcid, subsysnqn, host_traddr, and host_iface. all six of them. she's thorough like that 😌

and here's the key detail, the part you cannot skip, bestie: parameters set to NULL will be ignored. periodt. 🙅♀️

🫶 like, if you pass NULL for something, it doesn't get checked at all — it's just not part of the vibe check. so pass the ones you care about, and NULL the rest.

---

⭐ RETURN ⭐

• true if there's a match 💖
• false otherwise 💀

that's it. that's the whole return. she ate and left no crumbs 🔥
