libnvme(9)

💖 NAME 💖

ok so bestie, meet struct nvme_ns_mgmt_args — it's the lil argument bundle you hand over for the NVMe Namespace Management command. that's it, that's the whole vibe. it's giving "i hold all the stuff you need to manage a namespace." 🎀

---

✨ SYNOPSIS ✨

struct nvme_ns_mgmt_args {
    __u32 *result;
    struct nvme_id_ns *ns;
    int args_size;
    int fd;
    __u32 timeout;
    __u32 nsid;
    enum nvme_ns_mgmt_sel sel;
    __u8 csi;
    __u8 rsvd1[3];
    void *rsvd2;
    struct nvme_ns_mgmt_host_sw_specified *data;
 };

like, that's the whole struct. no notes. 💅

🌸 Members 🌸

okay so here's the cast of characters, each one doing its own main character moment:

• result — the NVMe command result. it's where the tea gets reported back to you. 🫖
• ns — Namespace identification descriptors. literally the ID card for your namespace. 🦋
• args_size — Size of struct nvme_ns_mgmt_args. yes babe, the struct knows how big it is. self-aware king. 👑
• fd — File descriptor of nvme device. that's your golden ticket into the device, don't lose it. 🎟️
• timeout — Timeout in ms. the patience meter. it's in milliseconds, so plan accordingly. ⏳
• nsid — Namespace identifier. which namespace are we even talking about? this one. 📛
• sel — Type of management operation to perform. the "what are we doing today" field. 🔥
• csi — Command Set Identifier. tells everyone which command set we're rolling with. 🌈
• rsvd1 — Reserved. hands off, that's not for you bestie. 🙈
• rsvd2 — Reserved. also not for you. also hands off. 💀
• data — Host Software Specified Fields. your custom lil payload, the personal touch. ⭐

fr fr: rsvd1 and rsvd2 are Reserved — do not touch, do not fill, do not get creative. that's the rule and we respect it. 🧚

k that's the whole page bestie, no cap. this was the libnvme(9) API Manual, and the page is dated August 2026 — so like, technically from the future, which is iconic of it honestly. mwah, go manage some namespaces. 💜✨
