STRUCT MUX_STATE(9)

💅 struct mux_state(9) — the kernel API manual, but make it make sense ✨

okay bestie, so this is a page from the Kernel API Manual and it's about struct mux_state — literally the glo-up era of mux controllers. let's get into it 🎀

---

🌸 NAME 🌸

struct mux_state — Represents a mux controller state specific to a given consumer.

like, it's giving "this state is yours, nobody else's" energy 💖

---

✨ SYNOPSIS ✨

struct mux_state {
    struct mux_control *mux;
    unsigned int state;
 };

no cap, that's the whole struct. two members, both iconic 👑

---

🫶 Members 🫶

• mux — Pointer to a mux controller. yup, that's the connection, the main character of the pair 💫
• state — State of the mux to be selected. this is the one you're picking, so choose wisely bestie 🌈

---

💅 Description 💅

This structure is specific to the consumer that acquires it and has information specific to that consumer. fr fr — it's your struct, it knows your stuff, it's not out here sharing your business with every other consumer in the kernel 😭

lowkey the whole point: the state info belongs to whoever grabbed it. periodt. 💀
