nfp_cpp_area_cache_add(9)

💅 nfp_cpp_area_cache_add — the kernel-API manual, bestie edition ✨

okay so you know how the manual name is nfp_cpp_area_cache_add(9)? yeah. that's the one. kernel API manual, section 9, and we're about to get into it 🎀

---

✨ NAME ✨

nfp_cpp_area_cache_add — permanently reserve an area for the hot cache 🔥

like, it grabs that space and it is not giving it back. periodt.

---

🌸 SYNOPSIS 🌸

int nfp_cpp_area_cache_add (struct nfp_cpp *cpp , size_t size );

---

🦋 ARGUMENTS 🦋

• cpp — the NFP CPP handle, your main character struct 💅
• size — the size of the area. and I need you to hear me on this one: it MUST BE A POWER OF 2. not "around" a power of two, not "basically" a power of two. a power of 2. no cap. 🫶

okay so about that "permanently reserve" thing — this is the reserve-and-keep-it-forever vibe, so don't come crying to me when it's still held later 😭
