nfp_cpp_explicit_acquire(9)

💅 nfp_cpp_explicit_acquire(9)

okay so first things first, bestie: this little cutie lives in the Kernel API Manual (yes, section 9, the driver-dev section, we stan) and the whole entire function name is nfp_cpp_explicit_acquire 🎀

---

✨ NAME ✨

nfp_cpp_explicit_acquire — acquire an explicit access handle 🫶

---

✨ SYNOPSIS ✨

struct nfp_cpp_explicit * nfp_cpp_explicit_acquire (struct nfp_cpp *cpp
);

like, that's the whole call. one argument. it hands you back a pointer to a struct nfp_cpp_explicit. no cap.

---

✨ ARGUMENTS ✨

• cpp — the NFP CPP handle 💖 (that's the one you're grabbing the explicit handle off of, obviously)

---

✨ DESCRIPTION ✨

okay so here's the tea 🍵 — the 'data_ref' and 'signal_ref' values are genuinely useful when you're constructing the NFP_EXPL_CSR1 and NFP_EXPL_POST values. that's it, that's the whole description, and honestly? iconic. short and slay. ✨

---

✨ RETURN ✨

an NFP CPP explicit handle 👑 (a struct nfp_cpp_explicit *, if we're being specific, and we are 💅)

💀 quick vibe check: if you acquire the explicit handle, go read nfp_cpp_explicit_release(9) too. that's your cleanup era. don't leave the handle hanging, bestie 😭
