💅 ecryptfs_miscdev_open(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual entry for ecryptfs_miscdev_open — no cap, it's a short one, and honestly? iconic for that. ✨

---

🌸 NAME 🌸

ecryptfs_miscdev_open — literally just the open handler, that's the whole vibe 🫶 (the original NAME section was genuinely blank after the dash, so like… we respect that)

---

🦋 SYNOPSIS 🦋

int ecryptfs_miscdev_open (struct inode *inode , struct file *file );

that's it, that's the signature, and it returns an int because of course it does 💀

---

✨ ARGUMENTS ✨

• inode — the inode of the miscdev handle. and like… it's ignored. completely. the function does not care. i'm sorry bestie, i don't make the rules 🙈
• file — the file for the miscdev handle. this one actually matters. main character energy 🌟

---

💖 DESCRIPTION 💖

the whole personality of this function: it returns zero on success, non-zero otherwise. periodt. 💅 that's the contract, that's the deal, nothing more to say, and honestly we love a low-stakes function that knows exactly what it is 🔥

lowkey a vibe check for whether opening the miscdev handle actually worked — zero means slay, anything else means 😭
