genlmsg_iput(9)

💖 genlmsg_iput — the Kernel API Manual, bestie edition 💖

Okay so this one lives in the kernel API manual (section 9, the fun one), and it's called genlmsg_iput. It's literally the "start a genetlink message based on a genl_info" girlie, and honestly? She's a convenience icon. 🌸

✨ NAME ✨

genlmsg_iput — start genetlink message based on genl_info 🎀

---

🦋 SYNOPSIS 🦋

void * genlmsg_iput (struct sk_buff *skb , const struct genl_info *info );

---

💅 ARGUMENTS 💅

• skb — the skb in which the message header will be placed. Like, that's where the header's going, no debate. 🫶
• info — the genl_info as provided to do/dump handlers. It's giving "handed to you by the core, bestie, use it." ✨

---

🌈 DESCRIPTION 🌈

So this is a convenience wrapper — a little shortcut function — which starts a genetlink message based on information in the user request. Very demure, very mindful. 💜

And here's the important part: info should be either the struct passed by the genetlink core to do/dump handlers (that's when you're constructing replies to such requests) or a struct initialized by genl_info_init_ntf when constructing notifications. Two valid moods, one function. Slay. 👑

---

💖 RETURN 💖

It returns a pointer to the new genetlink header. That's it, that's the whole vibe check. 🎯

Heads up bestie: this page is from ./include/net, and the date on it is October 2026. So when you're citing her, that's the era. ⭐

And that's the whole page, periodt. 🧚 Big kiss to ./include/net for hosting her, and to that October 2026 timestamp for keeping it real — go forth and start those genetlink messages, bestie. 💅💖🍓
