stratix10_sv...are_response(9)

💅 stratix10_svc_async_prepare_response — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, specifically the Kernel API Manual, and you've stumbled onto stratix10_svc_async_prepare_response(9). Don't panic. She's actually so chill once you get to know her. Let's get into it ✨

---

🌸 NAME 🌸

stratix10_svc_async_prepare_response — literally here to prepare the response data for an asynchronous transaction. that's her whole job. that's the assignment. she ate 💅

---

✨ SYNOPSIS ✨

int stratix10_svc_async_prepare_response (struct stratix10_svc_chan
*chan , struct stratix10_svc_async_handler *handle , struct
stratix10_svc_cb_data *data );

like yes she returns an int, and yes she takes three pointers. iconic behavior tbh 🫶

---

🎀 ARGUMENTS 🎀

• chan — Pointer to the service channel structure. this is the vibe check of channels fr fr 🦋
• handle — Pointer to the asynchronous handler structure. the async handler in question, she's the main character here ngl 👑
• data — Pointer to the callback data structure. where the good stuff ends up living 💖

---

🌈 DESCRIPTION 🌈

okay so what does she actually do. This function prepares the response data for an asynchronous transaction. like, that's the whole plot 🍓

She extracts the response data from the SMC response structure and stores it in the callback data structure. extraction!! very demure, very mindful 🧚

And bestie, she also logs the completion of the asynchronous transaction. so you get your little log line, your little closure, your little "it's done" moment. we love a function that journals 📝✨

---

⭐ RETURN ⭐

• 0 on success — slay 💅
• -ENOENT if the command is invalid — not slay, but she's honest about it 😭

fr fr, if you see -ENOENT you passed her something invalid, no cap. go check that command 👀
