ns_tree_node_empty(9)

💅 ns_tree_node_empty — a Kernel API Manual moment

ok so bestie, welcome to the Kernel API Manual entry for ns_tree_node_empty — it's a 9-section page (well, section 9, the kernel API one, you get it 💖) and honestly it's short and iconic and we love that for it.

---

✨ NAME ✨

ns_tree_node_empty — the little function that checks whether a namespace tree node is empty 🎀

---

🌸 SYNOPSIS 🌸

bool ns_tree_node_empty (const struct ns_tree_node *node );

like, that's the whole thing. no notes. ate. 👑

---

🦋 ARGUMENTS 🦋

• node — the node you're checking, bestie. that's the one. that's the node. 🫶

---

⭐ DESCRIPTION ⭐

ok so here's the whole vibe: it returns true if the node is not in any tree. yes, that's the entire description and no we are not elaborating, the manpage said what it said 💀

lowkey obsessed with how short this is. no cap, it's giving "I said what I said" energy.
