💅 iio_gts_get_total_gain — kernel API manual, but make it cute

okay so bestie, you're looking at iio_gts_get_total_gain(9) — a kernel function from the man page fam, and honestly? she's a little math gremlin and I'm obsessed. Let me walk you through it 🫶

✨ NAME ✨

iio_gts_get_total_gain — Fetch total gain for given HW-gain and time

like literally, that's the whole plot: you hand her a hardware gain and an integration time, she goes and finds the total gain for that combo. queen behavior 👑

🦋 SYNOPSIS 🦋

int iio_gts_get_total_gain (struct iio_gts *gts , int gain , int time );

yep that's it, that's the whole signature. no cap, four things: a return type, a descriptor, and two ints. she's lowkey minimal 🎀

🌸 ARGUMENTS 🌸

  • gts — the Gain time scale descriptor 💖 this is the context object, the main character of the whole operation, she holds all the info you need.
  • gain — the HW-gain for which the total gain is searched for 🔍 like, the hardware gain value you're feeding in so she can go hunt down the matching total gain.
  • time — the Integration time for which the total gain is searched for ⏱️ the second half of the search key, the time value in the same little lookup. gain + time = the vibe check, and she finds the total gain that passes it ✨

💀 RETURN 💀

  • total gain on success 🎉 you got your number, slay
  • -EINVAL on error 😭 something was invalid, bestie, and it did not work out — handle it fr fr
ngl, always check your return value. don't just assume she returned a gain and go about your day, because -EINVAL will absolutely humble you 🙈

okay this is the part where I introduce you to the entire friend group. it's a big friend group. it's giving group chat with 25 people and honestly they're all iconic 👑

the kernel file this lives in is ./drivers/iio/industrialio-gts-helper.c — that's home base 🏠 and here are her besties:

like I said — huge friend group, all of them relevant, none of them skipped 💅 go read them, iykyk 📚

🎀 the sign-off 🎀

this one came out of the ./drivers/iio corner of the kernel, dated October 2026, and it's filed under the Kernel API Manual. go off, industrial I/O gain-time-scale helper code, you absolute legend 🌈⭐💜

periodt. now go call iio_gts_get_total_gain responsibly 🦋✨
