🎀 Members 🎀

okay so like, meet the whole squad, one field at a time 🫶

• dom_id — the Domain Identifier. it's giving "which domain am I" energy 🪪
• rsvd2 — Reserved. nothing to see here, it's just vibing 🙈
• dom_cap — the Total Domain Capacity. lowkey the main character of this struct 👑
• unalloc_dom_cap — the Unallocated Domain Capacity. aka the capacity that hasn't been claimed yet ✨
• max_egrp_dom_cap — the Max Endurance Group Domain Capacity. say that five times fast, I dare you 😭
• rsvd64 — Reserved. more reserved than me at a party fr fr 💀

no cap: those rsvd* fields are Reserved. don't go writing your own lore into them, bestie, they're not yours to fill 🌸

and that's the whole page, periodt 💜 this was libnvme(2), the API manual, from back in July 2026 — mwah, slay, go forth and query your domains 🦋
