plist_node_empty(9)

💅 plist_node_empty — the Kernel API Manual moment 🎀

okay so bestie, this one is from the Kernel API Manual (that's the manual name, we're not copying the header line, we're just ✨acknowledging✨ it), and it's literally the tiniest little vibe check in the whole plist family. Let me tell you about it 🫶

🌸 NAME 🌸

plist_node_empty — returns !0 if plist_node is not on a list

yes you read that right, the naming is giving chaotic-but-iconic 💀 it's "empty" but the doc line says it returns !0 when the node is not on a list. Do not ask me to explain the branding, I just report it fr fr. Copy the behaviour exactly, don't second-guess it.

✨ SYNOPSIS ✨

int plist_node_empty (const struct plist_node *node );

that's it. that's the whole function signature. no cap, she's small but she's main character energy 👑

---

🦋 ARGUMENTS 🦋

• node — a struct plist_node pointer 💖 (this is the node you're asking about, the one you want the empty-or-not tea on)
