nla_put_u16(9)

💅 nla_put_u16 💅

okay so bestie, welcome to the <pink>Kernel API Manual</pink>, section 9 — today's main character is nla_put_u16, and honestly? she's a tiny little icon. one job, does it well, no drama. 🎀

---

✨ NAME ✨

nla_put_u16 — add a u16 netlink attribute to a socket buffer 🦋

like, that's it. that's the whole vibe. you got a 16-bit unsigned number and you need it to live inside a netlink attribute? she's the girl for the job. periodt.

---

🌸 SYNOPSIS 🌸

int nla_put_u16 (struct sk_buff *skb , int attrtype , u16 value );

three things in, one int out. returning an int is giving "check me before you move on" energy, iykyk. 😌

---

💖 ARGUMENTS 💖

• skb — the socket buffer you're adding the attribute to. this is the canvas, the blank page, the group chat you're about to send into. 🫶
• attrtype — the attribute type. basically the label on the box so everyone knows what's inside. 👑
• value — the numeric value. your actual u16 payload, the reason we're all here. literal star of the show. ⭐

🔥 SEE ALSO 🔥

bestie. buckle up. this list is long and we are NOT skipping a single one, because every single one of these is part of the netlink family and they all deserve their flowers. 🌈
