free_netbuf(9)

💖 free_netbuf(9) — the kernel API manual, bestie edition 💖

Okay so real talk, this little cutie lives in the free_netbuf(9) corner of the Kernel API Manual, and tbh it does exactly one thing and does it iconically 💅

---

✨ NAME ✨

free_netbuf — unmap and free a network buffer 🦋

Lowkey the whole personality: unmap it, free it, bye.

---

🌸 SYNOPSIS 🌸

void free_netbuf (void *buf );

That's it, that's the whole vibe. Returns void, so no receipts, no return value, nothing to check — it just goes ✨

---

🎀 ARGUMENTS 🎀

• buf — the buffer 🫶 like, the network buffer in question. That's the argument. That's the assignment.
