nvme_ctrl_set_tls_key(2)

💖 nvme_ctrl_set_tls_key — bestie's guide to the libnvme API manual (section 2, the syscall-ish zone) ✨

okay so real talk, this is a page from the libnvme API manual and it's about exactly one (1) function: setting the Derive TLS PSK on your controller. that's it. that's the whole vibe. let's get into it 🎀

---

🌸 NAME 🌸

nvme_ctrl_set_tls_key — set that Derive TLS PSK, periodt 💅

---

✨ SYNOPSIS ✨

void nvme_ctrl_set_tls_key (nvme_ctrl_t c , const char *key );

it returns void, bestie. nothing comes back. no int, no error code, no little "hey it worked" note. you just call it and you move on with your life 🦋

---

🫶 ARGUMENTS 🫶

• c — the Controller you want the key set on. like, which controller are we doing this to. that one. 👑
• key — the key itself, in interchange format. or you can pass NULL to clear out a key that already exists. yeah, NULL is the "nvm bestie, wipe it" option 🌈

---

⚠️ heads up: this function hands back literally nothing — it's void, so there's no return value to check on. the manual doesn't promise you any error reporting here, so don't go looking for one. 💀

---

and that's the whole page, no cap. shoutout to the libnvme API manual for hosting this little function, and big love to the July 2026 release of nvme_ctrl_set_tls_key — she's serving TLS PSK realness and she ate, fr fr 💖✨🎀
