iio_gts_valid_gain(9)

💅 iio_gts_valid_gain — Kernel API Manual, bestie edition ✨

okay so real talk, this page is from the Kernel API Manual and it's literally just one tiny little vibe-check function, but it's so important, so let's get into it 🎀

---

✨ NAME ✨

iio_gts_valid_gain — check if given HW-gain is valid 💖

like, that's it. that's the whole job. it checks a gain. for validity. iconic behavior honestly 🫶

---

🌸 SYNOPSIS 🌸

bool iio_gts_valid_gain (struct iio_gts *gts , int gain );

it gives back a bool, so you already know it's a yes-or-no situation, no in-between, no "it's complicated" 😌

---

🦋 ARGUMENTS 🦋

• gts — the Gain time scale descriptor 👑 this is the main character, the context object that knows all the gain/time-scale lore
• gain — the HW-gain you want to check 🔥 like, the actual number you're asking about

---

💀 RETURN 💀

• True — the given time is supported by the device ✅
• False — nope, not supported, try again bestie 🙈

ok ngl the original literally says "True if given time is supported by device. False if not." — yes, time, on a page about gain. we're not gonna fix it, we're just gonna notice it and move on 💅 iykyk
