nvme_ctrl_g...hap_host_key(2)

✨ NAME ✨

nvme_ctrl_get_dhchap_host_key — bestie, this one just hands you back the host key 💖

It's living in the libnvme API manual, and honestly? It's giving "short and sweet and does exactly one thing." Periodt.

---

🌸 SYNOPSIS 🌸

const char * nvme_ctrl_get_dhchap_host_key (nvme_ctrl_t c );

That's it. One function, one argument, one const char * coming back atcha 🦋

---

🎀 ARGUMENTS 🎀

• c — the Controller we're checking, aka the one you want to snoop on for its host key. Pass the controller and let the function do its lil thing 💅

---

💫 RETURN 💫

It returns the DH-HMAC-CHAP host key — yay! 🎉

And if there isn't one set? You get NULL. No host key, no vibes, just NULL. Not an error, not a crash, just the universe gently telling you "nah, nothing's set here" 😭

---

Heads up bestie: NULL means not set. That's a whole regular outcome, not a bug, not a breakdown. Check for it and keep it moving 💀

---

and that's the whole page, no cap 🫶

This little cutie comes to you courtesy of the libnvme source, dated July 2026, and it's chillin' in section 2 of the manual — the libnvme API manual, if you wanna be formal about it 👑

bye bestie, go get that host key ✨👑💜
