netlbl_cache_invalidate(9)

💅 netlbl_cache_invalidate(9) — like, the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the kernel, specifically the NetLabel corner of it, and you need every single protocol cache to just… forget everything it knows. That's this function. Welcome to the netlbl_cache_invalidate page, sponsored by the Kernel API Manual, no cap ✨

🌸 NAME 🌸

netlbl_cache_invalidate — the lil cleanup crew that invalidates all of the NetLabel protocol caches 🧹💖

---

✨ SYNOPSIS ✨

void netlbl_cache_invalidate (void );

that's it. that's the whole vibe check. 🫶

---

🦋 ARGUMENTS 🦋

• void — no arguments, bestie. literally none. she takes nothing and she gives everything 💅

---

💜 DESCRIPTION 💜

okay so here's the tea ☕ — for all of the NetLabel protocols that support some form of label mapping cache, this function invalidates the cache. Like, every single one of them that's got a cache to speak of. gone. poof. iconic behaviour honestly 🔥

and then — and this is the part where you gotta squint a little 👀 — it says: returns zero on success, negative values on error. Yeah. Even though the signature says void. That's what the page says, and we are not editorialising, we're just reporting fr fr 😭

the way that a void function has return values in the description is lowkey giving main character energy 💀 just roll with it
