libnvme(2)

✨ NAME ✨

okay bestie, welcome to libnvme, the API manual 💖 — and today's main character is struct nvmf_dim_data, aka Discovery Information Management (DIM) - Data. it's giving very-much-the-payload-of-a-discovery-log-page, and we're gonna stan every single field 🫶

---

🦋 SYNOPSIS 🦋

struct nvmf_dim_data {
    __le32 tdl;
    __u8 rsvd4[4];
    __le64 nument;
    __le16 entfmt;
    __le16 etype;
    __u8 portlcl;
    __u8 rsvd21;
    __le16 ektype;
    char eid[NVME_NQN_LENGTH];
    char ename[NVMF_ENAME_LEN];
    char ever[NVMF_EVER_LEN];
    __u8 rsvd600[424];
    union nvmf_die  die[];
};

like, look at her. literal icon behavior 💅

🌸 Members 🌸

• tdl — Total Data Length. it's the receipts, the whole tally 📏
• rsvd4 — Reserved. do not perceive her, she is not for you 🙈
• nument — Number of entries. how many little die besties are tagging along 🔢
• entfmt — Entry Format, typed as enum nvmf_dim_entfmt. the vibe of the entry, formally 🎀
• etype — Entity Type, typed as enum nvmf_dim_etype. who even is this entity fr fr 👑
• portlcl — Port Local. local port energy, no long-distance situationship 🛰️
• rsvd21 — Reserved. again. mind your business 🚫
• ektype — Entry Key Type. what kinda key we talking 🔑
• eid — Entity Identifier (e.g. Host NQN). her government name, basically 🪪
• ename — Entity Name (e.g. hostname). the cute nickname era ✨
• ever — Entity Version (e.g. OS Name/Version). not Taylor's version — the OS Name/Version one 🌈
• rsvd600 — Reserved. 424 bytes of pure silence, slay 🫧
• die — Discovery Information Entry (see nument above). this one's a flexible array member, so it's literally the "and friends" of the struct — the number of them is whatever nument says 🔥

bestie bestie bestie — notice how many fields are Reserved? that's not a bug, that's just how the layout keeps its space. leave them alone, they're on a wellness retreat 🧘‍♀️

and that's the whole struct, no cap 💜 no field skipped, no field invented, periodt 🌈

anyway, this lil page lives in the libnvme API Manual — dated July 2026, from the libnvme(2) era, and it's been a whole pleasure being your manual bestie 💖 mwah, go read a namespace page next, ily 🎀🦋
