libnvme(9)

✨ NAME ✨

struct nvme_ns_attach_args — the lil argument bundle for the Nvme Namespace Management command 🎀

okay bestie so this is a page from the libnvme API manual (that's the libnvme(9) manual section, iykyk) and it's literally just the one struct. one struct. and she is everything. let's get into it 💅

---

🌸 SYNOPSIS 🌸

struct nvme_ns_attach_args {
    __u32 *result;
    struct nvme_ctrl_list *ctrlist;
    int args_size;
    int fd;
    __u32 timeout;
    __u32 nsid;
    enum nvme_ns_attach_sel sel;
 };

no cap, that's the whole thing. seven members, zero drama 🦋

💖 Members 💖

• result — the NVMe command result. this is where the answer comes back to you, babe ✨
• ctrlist — the controller list that's gonna get its attachment state modified for nsid. yes, the list. the one you're messing with 👑
• args_size — the size of struct nvme_ns_attach_args. it's giving "struct knows its own size" and honestly? self-aware icon behavior 💅
• fd — file descriptor of the nvme device. you gotta have the fd. always the fd 🫶
• timeout — timeout in ms. milliseconds, bestie. don't let her hang forever 😭
• nsid — Namespace ID to execute attach selection. like, which namespace are we doing this attach thing to 🌸
• sel — Attachment selection, see enum nvme_ns_attach_sel. the selection. the vibe check of attach modes ✨

lowkey important: sel is an enum nvme_ns_attach_sel, so go read that enum before you start guessing what to put there. no improvising 🙈

and that's the whole page, bestie! 🌈 this one came from the libnvme API manual, dated August 2026, and it's filed under struct nvme_ns_attach_args in libnvme(9). go forth and attach some namespaces 💖🎀🦋✨
