genlmsg_cancel(9)

heyyy bestie 💖 welcome to the genlmsg_cancel(9) page — it's giving Kernel API Manual energy, and we're gonna get you comfy with it. No cap, this one is short and sweet.

✨ NAME ✨

• genlmsg_cancel — Cancel construction of a generic netlink message

Like, it's literally the "okay actually never mind" button for a generic netlink message you were building. Slay.

---

🎀 SYNOPSIS 🎀

The whole signature is right here, bestie:

void genlmsg_cancel (struct sk_buff *skb , void *hdr );

It's void, so no return value to catch. Periodt.

---

🦋 ARGUMENTS 🦋

Okay so there are exactly two arguments, and they're both lowkey essential:

• skb — socket buffer the message is stored in
• hdr — generic netlink message header

That's it. That's the whole cast. Main character energy from both of them, fr fr.
