lbs_cmd_copyback(9)

💖 lbs_cmd_copyback(9) — Kernel API Manual 💖

okay bestie, so this page is literally about lbs_cmd_copyback — it's the simple callback that copies response back into command ✨ no cap, that's the whole vibe. it's a little helper that takes the reply you got and shoves it back into the command struct. iconic behavior honestly 🫶

✨ SYNOPSIS ✨

int lbs_cmd_copyback (struct lbs_private *priv , unsigned long extra ,
       struct cmd_header *resp );

that's the whole signature, copy it exactly, don't freestyle 💅

🎀 ARGUMENTS 🎀

• priv — a pointer to the struct lbs_private structure 💖 like, the main character of the whole driver, iykyk.
• extra — a pointer to the original command structure for which (yes, the original text lowkey trails off there, we're keeping it fr fr) 🦋
• resp — a pointer to the command response 🌸 the thing that came back from the hardware.

👑 RETURN 👑

0 on success, error on failure ⭐ that's it, that's the whole contract. check it, always.
