nla_get_in_addr(9)

💖 NAME 💖

okay so bestie, welcome to nla_get_in_addr(9) — that's the Kernel API Manual, section 9, and this page is literally just one little function.

nla_get_in_addr — return payload of IPv4 address attribute ✨

that's it. that's the whole gig. it reaches into an attribute and hands you back the IPv4 address payload. iconic, minimal, no notes. 🎀

---

✨ SYNOPSIS ✨

__be32 nla_get_in_addr (const struct nlattr *nla );

literally one line, one function, one __be32 coming back at you 🫶 (copy it exactly bestie, don't get creative with the spaces, the manpage gods are watching 👀)

---

🌸 ARGUMENTS 🌸

• nla — the IPv4 address netlink attribute 💅 that's the thing you're feeding in. it's a netlink attribute specifically for an IPv4 address, and it's const struct nlattr *, so like... don't be weird about it.

ngl there's only one argument. this function is lowkey living its simplest life and honestly? we love that for it. 😌

anyway bestie, that's the whole page 🦋 this one came out of ./include/net and it's stamped October 2026 — so mark your calendar, the netlink girlies stay current. mwah, go read netlink.h and slay 💋💖🧚
