nfp_cpp_area_writel(9)

💅 nfp_cpp_area_writel(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — yes, that's the manual name, it's giving "official documentation but make it cute". Today's main character is nfp_cpp_area_writel, and honestly? She's a simple queen with one job. Let's get into it 🎀

---

🌸 NAME 🌸

nfp_cpp_area_writel — writes a u32 word into an area. that's it. that's the whole gig. 💖

---

✨ SYNOPSIS ✨

int nfp_cpp_area_writel (struct nfp_cpp_area *area , unsigned long
offset , u32 value );

lowkey a whole function signature, but it's fine, we love a one-liner 🫶

---

🦋 ARGUMENTS 🦋

• area — your CPP Area handle, aka the ✨vibe✨ you're writing into. hold onto it, bestie, it's the whole point.
• offset — where inside the area you're dropping your word. it's an offset into the area, so like, know your coordinates 🧚
• value — the actual value you wanna write. a u32 word of pure content. slay 💅

---

🌈 RETURN 🌈

0 on success, or -ERRNO if things got messy 😭 (that's the classic kernel way of saying "it's giving problems").

ngl that's a lot of cross-references but every single one of them is iconic in her own way 🔥
