✨ libnvme — struct nbft_info_host 💖

okay bestie, welcome to the libnvme manual, section 2 (that's the system-call / API girlies section, iykyk). today's main character is a lil struct called nbft_info_host, and she's giving Host Descriptor energy. literally obsessed. let's get into it 🫶

---

🌸 NAME 🌸

struct nbft_info_host — Host Descriptor 👑

---

🦋 SYNOPSIS 🦋

struct nbft_info_host {
    unsigned char *id;
    char *nqn;
    bool host_id_configured;
    bool host_nqn_configured;
    enum nbft_info_primary_admin_host_flag primary;
 };

🎀 Members 🎀

• id — the Host ID, bestie. it's a raw UUID and its length is exactly 16 bytes. no more, no less, periodt.
• nqn — the Host NQN. that's it, that's the field 💅
• host_id_configured — the HostID Configured Flag. if this is True, that means id is holding an administratively-configured value. if it's False, then id is just the driver default value instead. no cap.
• host_nqn_configured — the Host NQN Configured Flag. same vibe as her sister up there: True means nqn contains an administratively-configured value, and False means it's the driver default value. 💖
• primary — the Primary Administrative Host Descriptor. for the deets you gotta go look at enum nbft_info_primary_admin_host_flag, she spills the whole tea 🌈

fr fr: every single one of these fields matters, so don't be skipping any of them. the flags are how you tell "someone deliberately set this" apart from "the driver just made it up on its own" — that's highkey important. 😭

and that's the whole page, bestie!! you ate that. this lil icon dropped back in July 2026, it's the struct nbft_info_host page from libnvme, section 2. mwah, go forth and slay your NBFT parsing 💅✨💜
