ubifs_wbuf_init(9)

💫 ubifs_wbuf_init(9) — like, the Kernel API Manual page, bestie 💫

Okay so real talk — this is a page straight out of the Kernel API Manual, and it's about one lil' function that gets a write-buffer all set up and ready to slay. That's it. That's the whole vibe. Let's go 🫶

---

✨ NAME ✨

ubifs_wbuf_init — literally just initializes a write-buffer. That's her only job and she does it 🎀

---

🌸 SYNOPSIS 🌸

int ubifs_wbuf_init (struct ubifs_info *c , struct ubifs_wbuf *wbuf );

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. Like, the whole file system's info in one struct, iykyk 💅
• wbuf — the write-buffer you're initializing. She starts out a blank canvas, and you're giving her a purpose ✨

---

💖 DESCRIPTION 💖

So what does she actually do? She initializes the write-buffer. Periodt. 💅

Returns zero if everything went off without a hitch — success, we love to see it 🎉 And if it flops? You get -ENOMEM. That's it, that's the whole return story 😭
