IIO_ENUM(9)

💖 IIO_ENUM 💖

okay so this is from the Kernel API Manual bestie, like the kernel's own lil doc for IIO_ENUM(9) — and we're gonna get through it together, no stress 🫶

---

✨ NAME ✨

IIO_ENUM — Initialize enum extended channel attribute 🌸

like, it's the thing that starts your enum extended channel attribute. that's the whole vibe.

---

✨ SYNOPSIS ✨

IIO_ENUM (_name , _shared , _e );

copy it exact, don't @ me, the spacing is the spacing 💅

---

✨ ARGUMENTS ✨

• _name — the attribute name. literally just what you're calling the thing 🎀
• _shared — whether the attribute is shared between all channels. yes bestie, all of them, or not, your call 👑
• _e — a pointer to an iio_enum struct. it's a pointer, so like, be normal about it 🙈

---

✨ DESCRIPTION ✨

so this one should usually be used together with IIO_ENUM_AVAILABLE 🌈

that's it, that's the tea. they're a matching set, iykyk. pairing them up is the move, and that's not me being extra, that's literally what the page says 🔥

real talk: "usually" is the word here — keep it in your brain exactly like that ⭐

✨ SEE ALSO ✨

okay this list is LONG, so buckle up, we're going through every single one, no skipping, we don't do that here 😭
