💅 kmx61_read_for_each_active_channel — the Kernel API Manual era

okay so bestie, welcome to the Kernel API Manual, and today's main character is kmx61_read_for_each_active_channel(9). yes the header truncates it to kmx61_read_f...tive_channel(9) — that's just the page title doing its little shy thing, the actual function name is the full one, iykyk. 🎀

✨ NAME ✨

kmx61_read_for_each_active_channel — literally reads each active channel into a buffer. that's the vibe. every active channel gets read, no channel left behind. 🦋

---

🌸 SYNOPSIS 🌸

int kmx61_read_for_each_active_channel (struct iio_dev *indio_dev , s16
*buffer );

so it takes an indio_dev and a buffer, and it returns an int. that's the whole signature, slay. ✨

---

💖 ARGUMENTS 💖

• indio_dev — the IIO Device struct you're reading from. it's giving source of truth, the one we're pulling data out of. 👑
• buffer — the destination buffer we write to. important: the array must be of at least size 8. not 7, not "close enough" — 8. periodt. 💅

---

🔥 RETURN 🔥

• 0 on success. iconic, we love a clean zero. ✅
• a negative errno on failure. 😭 so if it's negative, something went sideways and the errno tells you what.

🧚 SEE ALSO 🧚

• Kernel file ./drivers/iio/imu/kmx61.c — the source, the icon, the blueprint 🫶
• kmx61_set_mode(9)
• kmx61_set_power_state(9)

ngl bestie, always double-check your buffer is at least size 8 before you call this. the docs said it, so I'm saying it. no cap. 🙈
