iio_channel_has_available(9)

💖 iio_channel_has_available — the Kernel API Manual, bestie edition 💖

okay so you're in the Kernel API Manual (that's the manual name, hi hello, welcome to the group chat 🌸) and the star of the show today is iio_channel_has_available(9). she's a lil boolean gatekeeper and honestly? iconic. let's get into it ✨

---

✨ NAME ✨

iio_channel_has_available — literally checks if a channel has an available attribute 🎀

like. that's it. that's her whole job. and she does it flawlessly, no cap.

---

🦋 SYNOPSIS 🦋

bool iio_channel_has_available (const struct iio_chan_spec *chan , enum
iio_chan_info_enum type );

she takes two things and hands you back a bool — the most main-character return type ever 💅

---

🍓 ARGUMENTS 🍓

• chan — the channel to be queried 👀 like, the one you're asking about. the it-girl in question.
• type — type of the available attribute to be checked 🔍 which flavour of "available" you're lowkey looking for.

---

🌈 DESCRIPTION 🌈

Returns true if the channel supports reporting available values for the given attribute type, false otherwise. periodt. 🫶

so: does this channel do available-values for this attribute type? yes → true 💚 no → false 💀 it's giving very binary, very decisive, very much "vibe check: passed or not." 😌✨

ngl bestie, this one's short and sweet — no scary caveats, no deprecated nonsense, no "undefined behaviour, do not pass go". just a clean little true/false check. slay. 💅
