cppi5_hdesc_get_swdata(9)

💅 cppi5_hdesc_get_swdata — like, the whole kernel API manual vibe ✨

okay bestie, so this is cppi5_hdesc_get_swdata(9) from the Kernel API Manual, and it's literally so simple it's iconic. let's get into it 🫶

---

🌸 NAME 🌸

cppi5_hdesc_get_swdata — get a pointer on swdata. that's it. that's the whole job. 💖

---

✨ SYNOPSIS ✨

void * cppi5_hdesc_get_swdata (struct cppi5_host_desc_t *desc );

no cap, one function, one argument, returns a void *. clean. 🎀

---

🦋 ARGUMENTS 🦋

• desc — the Host packet descriptor. like, the hdesc itself, bestie. hand it over 💅

---

🌈 RETURN 🌈

a pointer on SWDATA in HDesc. periodt.

⚠️ NOTE, and this is the important part: it's the caller's responsibility to be sure the hdesc actually has swdata. not the function's. yours. so, like, do your vibe check first, bestie 😭 — this function will not check for you and there's no plan B here.
