ubifs_auth_node_sz(9)

✨ ubifs_auth_node_sz(9) — like, the Kernel API Manual said let her cook ✨

okay so bestie, welcome to the glow-up edition of ubifs_auth_node_sz(9), fresh out of the Kernel API Manual and honestly? iconic. she's a tiny little function but she knows exactly what she's about 💅

---

🌸 NAME 🌸

ubifs_auth_node_sz — returns the size of an authentication node. that's it. that's the whole job. she measures one (1) auth node and goes home 🎀

---

⭐ SYNOPSIS ⭐

int ubifs_auth_node_sz (const struct ubifs_info *c );

yes she takes exactly one (1) argument, yes she returns an int, no she will not be elaborating 🫶

---

💖 ARGUMENTS 💖

• c — the UBIFS file-system description object. your whole entire filesystem vibe, condensed into one struct. she needs it, she reads it, no cap 🌈

---

👑 RETURN 👑

so like, she hands back the size of an authentication node, and here's the tea: that number can be 0 for unauthenticated filesystems 😌 or it's the real size of an auth node when authentication is enabled. so basically 0 means "auth? never met her" and anything else means "auth is ON and this is how much room she takes up" ✨
