💅 genlmsg_reply(9) — the Kernel API Manual, section 9, bestie

okay so picture this: you're deep in the kernel, someone slid a netlink request into your DMs, and now you need to clap back. that's literally what this function is for. it's from the Kernel API Manual, section 9 (kernel routines), and it's giving "reply to a request" main character energy. 🎀

✨ NAME ✨

genlmsg_reply — reply to a request 💌

like, the whole entire job. no notes. periodt.

---

🌸 SYNOPSIS 🌸

int genlmsg_reply (struct sk_buff *skb , struct genl_info *info );

yes bestie, the return type is int, and the spacing in there is exactly how it's written, don't come for me 🫶

---

🦋 ARGUMENTS 🦋

• skb — the netlink message to be sent back 🔥 this is the actual thing you're yeeting back to whoever asked. it's the struct sk_buff *, so it's the packet, it's the vibe, it's the answer.
• info — receiver information 👑 all the deets about who's on the other end, wrapped up in a struct genl_info *.

two arguments. that's it. that's the whole menu. iconic of her honestly 💅

ngl this page is short, but short is chic. don't go inventing extra parameters, the signature is the signature fr fr.
