nvme_ctrl_find(2)

💖 nvme_ctrl_find — libnvme API manual, bestie edition 💖

okay so you're reading the nvme_ctrl_find(2) page from the libnvme API manual and honestly? good for you. this is the glow-up your controller lookups deserved. ✨

---

🎀 NAME 🎀

nvme_ctrl_find — locate an existing controller. that's it. that's the whole job. she finds controllers. 👑

---

🌸 SYNOPSIS 🌸

nvme_ctrl_t nvme_ctrl_find (nvme_subsystem_t s , const char *transport ,
const char *traddr , const char *trsvcid , const char *subsysnqn , const
char *host_traddr , const char *host_iface );

seven args. seven little besties you gotta hand over. no cap. 💅

---

🦋 ARGUMENTS 🦋

• s — an nvme_subsystem_t object. this is the plaza you're shopping in, the whole vibe container you're searching inside 🫶
• transport — transport name. literally what it says on the tin ✨
• traddr — transport address. where the transport lives 📍
• trsvcid — transport service identifier. yes it's a mouthful, we love her anyway 🎀
• subsysnqn — subsystem NQN. the NQN of the subsystem, iconic identifier behavior 💜
• host_traddr — host transport address. the host side of the whole situation 🌈
• host_iface — host interface name. name of the host interface, periodt 💫

---

🌟 DESCRIPTION 🌟

so the tea is: you look up a controller in s based on transport, traddr, trsvcid, subsysnqn, host_traddr, and host_iface. all six of them, matching against s. simple. elegant. obsessed. 💖

transport is the one that must be specified — like, non-negotiable, she has to be there. the other fields may be required depending on the transport, so don't assume you can ghost them 🚫👻

anything you set to NULL gets ignored. not matched against, not complained about, just straight-up ignored bestie 🙈

and now the plot twist that you NEED to know: unlike nvme_lookup_ctrl, this function does not create a new object if an existing controller cannot be found. she does not manifest. she does not improvise. if it's not there, it's not there. 😭

---

⭐ RETURN ⭐

• controller instance on success 🥳
• NULL otherwise 💀

that's the whole vibe check.

okay that's the page, mwah 💋
