libnvme(9)

✨ NAME ✨

okay bestie so libnvme is the API manual for the libnvme crew, and today's main character is struct nvme_io_mgmt_recv_args — it's literally the arguments for the NVMe I/O Management Receive command. that's it, that's the vibe. 💖

---

🦋 SYNOPSIS 🦋

no cap, here's the whole struct, every field, exactly as it lives:

struct nvme_io_mgmt_recv_args {
    void *data;
    int args_size;
    int fd;
    __u32 nsid;
    __u32 data_len;
    __u32 timeout;
    __u16 mos;
    __u8 mo;
 };

---

💅 Members 💅

okay so let's meet the squad, one field at a time. no skipping, no summarizing, we're doing all of them fr fr 🫶

• data — the userspace address of the data. it's giving "here's where the goods live" 🌸
• args_size — the size of struct nvme_io_mgmt_recv_args itself. yes she measures herself, iconic behavior 👑
• fd — file descriptor of the nvme device. your lil ticket to the device, periodt 🎀
• nsid — namespace identifier. gotta know which namespace we're talking to 💜
• data_len — length of data. how much data, that's the whole thing 🦋
• timeout — timeout in ms. patience is a virtue but also a number ✨
• mos — Management Operation Specific. lowkey the spicy detail field 🌈
• mo — Management Operation. the main operation itself, main character energy 💅

---

bestie reminder: all those numbers stay exactly as written up there — __u32 is not a suggestion and __u16 vs __u8 is not a typo, do not touch them 🙈

and that's the whole page, no notes. this lil rewrite is living in the API Manual, filed under libnvme(9), and the source/date stamp on the original footer was August 2026 — so yeah, shoutout to August 2026 for keeping the receipts. bye bestie, go call your ioctl 💖✨🎀
