libnvme(9)

✨ NAME ✨

okay bestie, so this is libnvme(9) from the API Manual (yes that's the manual section, she's fancy like that) 💅 and the star of this page is struct nvme_io_mgmt_send_args — literally just the arguments you hand over for the NVMe I/O Management Send command. that's it. that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

here's the struct in all her glory, no cap:

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

she's giving main character energy with eight members and not one of them is optional fluff ✨

🌸 Members 🌸

okay so let's go through every single one because we do NOT skip members in this house 🙈

• data — the userspace address of the data. it's a void *, so she's mysterious, she's flexible, she contains multitudes 💜
• args_size — the size of struct nvme_io_mgmt_send_args itself. yes she measures herself, self-aware queen 👑
• fd — the file descriptor of the nvme device. your little handle to the hardware, your connection, your whole world lowkey 🫶
• nsid — the namespace identifier. it's a __u32, and it tells everyone which namespace we're talking to 🌈
• data_len — the length of data. how much data, exactly? this much. __u32 much. ⭐
• timeout — timeout in ms. milliseconds, bestie. don't make her wait forever 💀
• mos — Management Operation Specific. it's a __u16, it's specific, it's doing its thing 🧚
• mo — Management Operation. just mo. __u8. tiny but mighty, iykyk 💖

fr fr every field matters, don't be out here leaving any of them uninitialized, that's not the energy we're bringing today 🌸
