nvme_create_ctrl(2)

✨ nvme_create_ctrl ✨

okay so bestie, we're in libnvme API manual territory, section 2, and today's main character is nvme_create_ctrl 💅 like yes, that's the whole function name, that's the vibe.

🌸 NAME 🌸

nvme_create_ctrl — allocate an unconnected NVMe controller 🎀

🦋 SYNOPSIS 🦋

nvme_ctrl_t nvme_create_ctrl (nvme_root_t r , const char *subsysnqn ,
const char *transport , const char *traddr , const char *host_traddr ,
const char *host_iface , const char *trsvcid );

look at her. seven params. absolute queen behavior 👑

💖 ARGUMENTS 💖

• r — the NVMe root element. your whole root thing, she lives here.
• subsysnqn — the Subsystem NQN 🫶
• transport — the transport type, as in what flavour of transport we're doing.
• traddr — the transport address. where we're pointing this thing at.
• host_traddr — the host transport address.
• host_iface — the host interface name 🌈
• trsvcid — the transport service ID ⭐

💅 DESCRIPTION 💅

So basically: this creates an unconnected controller — not connected yet, just… existing, existing beautifully — and the whole point is that it's meant to be used for nvme_add_ctrl later on. it's giving setup era, not commitment era 🙈

🎀 RETURN 🎀

A Controller instance 🔥 that's it, that's the gift.

---

lowkey important: no cap, this one's literally just handing you the controller so nvme_add_ctrl can do the actual connecting. don't skip that step bestie 😭
