nilfs_segctor_construct(9)

💖 NAME 💖

nilfs_segctor_construct — the girlboss that forms logs and then writes them to disk ✨

ok so real talk, this page lives in the Kernel API Manual section (section 9, kernel-functions land 🎀), and the whole vibe is: you hand it a segment constructor object, you tell it how to form the log, and it goes and does the thing. no cap.

---

🌸 SYNOPSIS 🌸

int nilfs_segctor_construct (struct nilfs_sc_info *sci , int mode );

that's the whole signature bestie, that's it, that's the function 💅

---

🦋 ARGUMENTS 🦋

• sci — the segment constructor object itself 🫶 like, the actual star of the show, the main character energy of this call.
• mode — the mode of log forming ✨ i.e. how the logs get formed. yes it's literally called "mode of log forming", she's not complicated.

---

🌈 RETURN 🌈

• 0 on success 💖 slay, we love a clean return
• a negative error code on failure 😭 not slay, but at least it's honest

ngl, this is the whole contract: zero means we ate, negative means something went sideways. no in-between, no vibes-based grading.
