nvme_write(2)

🌸 nvme_write — okay bestie, listen up

Hi hi hiii 💖 welcome to the nvme_write(2) page from the libnvme API manual. Yes, it's a real manual page, yes it's short, no we're not skipping a single crumb of it. Periodt.

---

✨ NAME ✨

nvme_write — submit an nvme user write command 🦋

That's it. That's the whole vibe. You're handing a write command to nvme and letting the kernel (and the drive) do their thing. Iconic honestly.

---

🎀 SYNOPSIS 🎀

int nvme_write (struct nvme_io_args *args );

One function, one argument, zero drama. The way she keeps it simple 💅

---

🫶 ARGUMENTS 🫶

• args — a struct nvme_io_args argument structure ✨ like, that's literally what it is, it's the structure you pass in and it carries all your io details. No cap.

---

👑 RETURN 👑

So here's what you get back, and this part is important, don't scroll past it:

• If a response actually came back, you get the nvme command status — and the manpage says to check enum nvme_status_field for what those values mean 🍓
• Otherwise you get -1, and errno is set so you know what went wrong 😭

fr fr bestie, always check errno when you see that -1. It's the difference between "the drive said no" and "something else entirely said no."

---

💜 quick vibe check

• function: nvme_write
• takes: struct nvme_io_args *args
• returns: nvme status, or -1 + errno
• manual section: 2 (that's a system call page, iykyk)

okay that's the whole page, we ate and left zero crumbs 🌈✨ This little love letter to nvme lived in the libnvme API manual, dated July 2026, filed under the name nvme_write and section nvme_write(2) — go forth and write some blocks, mwah 💖🦋🎀
