iio_channel_has_info(9)

✨ iio_channel_has_info ✨

okay bestie, so this is a page out of the Linux Kernel API Manual, and it's about iio_channel_has_info — cute little helper that answers one very specific question for you: does this channel vibe with this info attribute or not? that's it, that's the whole gig 💅

---

🌸 NAME 🌸

iio_channel_has_info — checks whether a channel supports a info attribute

ngl the original says "a info" and i'm keeping it because it's iconic and i don't make the rules 🎀

---

🦋 SYNOPSIS 🦋

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

like literally that's it. one bool coming right at you, two args going in. slay ✨

---

💖 ARGUMENTS 💖

• chan — the channel you're interrogating, bestie. it's a const struct iio_chan_spec * and it's the thing being queried. be nice to it, it's const.
• type — the type of the info attribute you want checked. it's an enum iio_chan_info_enum, so pick your fave from the enum and let the function do its thing.

---

🎀 DESCRIPTION 🎀

okay so here's the tea 🍵 — this function returns true if the channel supports reporting values for the given info attribute type, and false otherwise.

that's the whole personality. no side effects, no drama, just a clean true/false. main character energy honestly 👑
