irdma_copy_ip_ntohl(9)

💅 irdma_copy_ip_ntohl 💅

okay so bestie, this is a page from the Kernel API Manual, section 9 (iykyk, that's the kernel devs' section ✨). And honestly? It's a little two-line legend that does exactly one job and does it flawlessly. No cap.

---

✨ NAME ✨

irdma_copy_ip_ntohl — copy IP address from network to host 🫶

Like, it takes your IP address out of its little network-order outfit and puts it in host-order clothes. A whole glow-up, but for bytes. 💅

---

🌸 SYNOPSIS 🌸

void irdma_copy_ip_ntohl (u32 *dst , __be32 *src );

That's it. That's the whole vibe. She returns void, she takes two pointers, she minds her own business. 👑

---

🦋 ARGUMENTS 🦋

• dst — the IP address, but in host order 💖 like, the cute normal-order version. This is where the copy lands.
• src — the IP address as it came in: network order (big endian) 🌈 the source she's copying from, endianness and all.

So it's literally src → dst, network → host. No swap-around, no surprises, just the one-way trip. 🧚
