💅 mux_control_states(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is mux_control_states, and honestly? she's short, she's sweet, and she does exactly one thing. we love a focused queen 👑

---

🌸 NAME 🌸

mux_control_states — Query the number of multiplexer states. that's it. that's the whole job. no cap 💅

---

✨ SYNOPSIS ✨

unsigned int mux_control_states (struct mux_control *mux );

literally just hand her a mux-control pointer and she'll tell you how many states it's got. simple. iconic. 🎀

---

🦋 ARGUMENTS 🦋

• mux — The mux-control to query. yeah, that's the one you're asking about. give her the goods and she'll do the rest 🫶

---

⭐ RETURN ⭐

The number of multiplexer states. that's the value that comes back — an unsigned int, bestie, so don't go expecting anything spicy 🔥

no error codes here, no weird edge cases spelled out — she returns the count and that's the vibe check ✅
