ubi_open_volume_path(9)

💅 ubi_open_volume_path(9) — like, the Kernel API Manual bestie edition ✨

okay so welcome to the group chat, this is the ubi_open_volume_path(9) page from the Kernel API Manual and it's honestly such a vibe 🦋 it's a lil function that opens a UBI volume but, and hear me out, by its path — icon behaviour, no cap.

---

✨ NAME ✨

ubi_open_volume_path — opens a UBI volume by its character device node path 💖 that's literally it, that's the whole thing, and she serves.

---

🎀 SYNOPSIS 🎀

struct ubi_volume_desc * ubi_open_volume_path (const char *pathname ,
int mode );

look at her go 😭 returns a struct ubi_volume_desc * and everything.

---

🌸 ARGUMENTS 🌸

• pathname — the path to the volume's character device node 🫶 like, the actual path string, bestie.
• mode — the open mode ⭐ that's the whole description, yes really, keep it moving.

---

💜 DESCRIPTION 💜

so this function is basically the sibling of ubi_open_volume — lowkey same energy — except instead of whatever that one does, this one opens a volume by the path to its character device node 🧚✨ path in, volume opened, slay.

"similar to" is doing a lot of work here but that's literally what the page says and I'm not gonna make stuff up, that's not the vibe 🙈

no cap: if you wanna open a volume the normal way, go read ubi_open_volume(9) — this one's the path-based remix 💅
