ecryptfs_verify_version(9)

💖 NAME 💖

okay so this is ecryptfs_verify_version(9), and we’re in the Kernel API Manual era of the lore.

ecryptfs_verify_version — and bestie, the one-line description after that dash is literally blank on this page. Minimalist icon behavior, honestly. 💅

✨ SYNOPSIS ✨

int ecryptfs_verify_version (u16 version );

---

🎀 ARGUMENTS 🎀

• version — the version number to confirm. That’s the whole assignment, no cap.

---

🦋 DESCRIPTION 🦋

Returns zero on good version; non-zero otherwise.

That’s it. That’s the plot. Zero = good version vibe check passed ✅. Non-zero = not it 😭.
