LIBNVME_CTRL_SET_KXCHAP_HOST_KEY-LIBNVME3(2)

💖 libnvme_ctrl_set_kxchap_host_key — bestie's guide to the libnvme API manual, section 9 🎀

okay so listen, this one is a tiny little function from the libnvme API manual (that's section 9 if you're keeping score), and it's honestly giving short and sweet. No cap, it's literally two arguments and a vibe. Let's get into it ✨

🌸 NAME 🌸

libnvme_ctrl_set_kxchap_host_key — set kxchap_host_key. That's it, that's the whole thing 💅

✨ SYNOPSIS ✨

void libnvme_ctrl_set_kxchap_host_key (struct libnvme_ctrl *p , const
       char *kxchap_host_key );

so it returns void (nothing comes back, it's not that kind of function, she's a doer 🫶), and she takes a pointer to a struct libnvme_ctrl plus a const char *. iconic.

🦋 ARGUMENTS 🦋

• p — the struct libnvme_ctrl instance you wanna update. like, this is the controller, the main character, the one we're setting the key on 👑
• kxchap_host_key — the new string! and listen: a copy is stored 🍓 so don't stress about the pointer's lifetime, she made her own copy, she's independent like that. and if you wanna just yeet it and start fresh, pass NULL to clear it. yup, NULL clears, no notes 💀

💜 a little sign-off 💜

this little cutie is from the October 2026 edition of the libnvme API manual — page libnvme_ctrl_set_kxchap_host_key, section 9, bestie. go set some keys, hydrate, and remember: copy is stored, NULL clears, periodt 🌈⭐🧚
