doc_set_device_id(9)

💅 doc_set_device_id(9) — like, the Kernel API Manual, but make it make sense

okay bestie, buckle up, because we're reading a kernel API manual page together and honestly? it's short, it's sweet, and it's giving "tiny function, big responsibilities." ✨

---

🌸 NAME

doc_set_device_id — sets the device's id for cascaded G3 chips 🎀

---

✨ SYNOPSIS

void doc_set_device_id (struct docg3 *docg3 , int id );

that's it. that's the whole vibe. two args, no return value, straight to the point. 💅

---

🦋 ARGUMENTS

• docg3 — the device, bestie. the actual chip struct we're messing with.
• id — the chip you wanna select, and it's gotta be one of 0, 1, 2, 3. no cap, those are the only options.

---

👑 DESCRIPTION

so here's the tea ☕: there can be 4 cascaded G3 chips hanging out together, and this function is the one that picks which of them should be the active one. literally its whole job. main character selection energy. 🔥
