aa_alloc_root_ns(9)

✨ aa_alloc_root_ns — the Kernel API Manual glow-up ✨

Okay bestie, gather round, because we're diving into the Kernel API Manual and today's main character is aa_alloc_root_ns. Yes, it's giving kernel-internals, yes it's lowkey iconic 💅

🌸 NAME 🌸

aa_alloc_root_ns — literally just allocate the root profile namespace. That's it, that's the vibe. 🎀

---

🦋 SYNOPSIS 🦋

int aa_alloc_root_ns (void );

No cap, this is the whole signature. Short, sweet, slays. ✨

---

💖 ARGUMENTS 💖

• void — no arguments, bestie. None. Zero. Nada. It takes nothing and it's not sorry about it 🙈

---

🔥 RETURN 🔥

• 0 on success 🎉 — the good ending
• else error — the not-so-good ending 😭 (i.e. anything that isn't 0 means it went sideways)
