hiii bestie 🫶 okay so we're in the Kernel API Manual today, and the page we're reading is all about nla_put_u32(9). Yes the whole manual is named nla_put_u32(9) — it's that girl, she's the main character of this page 💅

🌸 NAME 🌸

nla_put_u32 — Add a u32 netlink attribute to a socket buffer

Like literally all it does is take a u32 netlink attribute and add it to a socket buffer. That's the whole vibe. Slay. ✨

🦋 SYNOPSIS 🦋

int nla_put_u32 (struct sk_buff *skb , int attrtype , u32 value );

no cap, that's the entire call signature — copy it character for character, bestie, don't get cute with the spacing 😭

🎀 ARGUMENTS 🎀

• skb — the socket buffer to add the attribute to. this is the canvas, the moment, the whole point 🖼️
