💅 dmub_srv_cmd_get_response(9) — a Kernel API Manual moment ✨

okay bestie, buckle up, we're diving into the dmub_srv_cmd_get_response page from the Kernel API Manual and honestly? it's a little cutie. 🎀

---

🌸 NAME 🌸

dmub_srv_cmd_get_response — literally copies the return data for a command into a buffer. that's it. that's the whole vibe. 💖

---

✨ SYNOPSIS ✨

void dmub_srv_cmd_get_response (struct dmub_srv *dmub , union
dmub_rb_cmd *cmd_rsp );

no cap, that's the signature. she takes two things and returns void because she's mysterious like that. 🦋

🫶 ARGUMENTS 🫶

• dmub — the dmub service. yes, the whole service. main character energy. 👑
• cmd_rsp — the response buffer. this is where the good stuff lands. 🍓

---

💜 DESCRIPTION 💜

okay so the description is honestly iconic in its brevity: copies return data for command into buffer. that's the entire plot. she copies the return data for a command into a buffer, and she does it flawlessly, periodt. 💅 no extra lore, no side quests — just data going from one place to another and looking gorgeous doing it. ✨
