befs_bt_read_super(9)

💖 befs_bt_read_super(9) — NAME 💖

okay so bestie, welcome to the Kernel API Manual entry for befs_bt_read_super — literally the function whose whole personality is read in btree superblock convert to cpu byteorder. That's it, that's the job. 🎀

---

✨ SYNOPSIS ✨

int befs_bt_read_super (struct super_block *sb , const befs_data_stream
*ds , befs_btree_super * sup );

---

🫶 ARGUMENTS 🫶

• sb — the filesystem superblock, obviously. your main character struct. 👑
• ds — the datastream we're reading from. the source, the origin story. 🌸
• sup — the buffer where we're gonna place the btree superblock. like a little designated seat for it. 💅

---

🦋 DESCRIPTION 🦋

So the way this works: it calls befs_read_datastream to read in the btree superblock, then it makes sure it's in cpu byteorder — byteswapping if necessary. no cap. 🔥

Byteswapping. on sight. if it needs it. it's giving "I checked the endianness and I handled it." periodt. ✨

---

🌈 RETURN 🌈

• BEFS_OK — slay! success, returned when *sup contains the btree superblock in cpu byte order. 💖
• BEFS_ERR — otherwise. on error. 😭 that's the whole vibe check.
