iio_update_buffers(9)

💅 iio_update_buffers(9) — like, the kernel API manual era 🎀

okay bestie so this one lives in the Kernel API Manual section of your man pages, and it's called iio_update_buffers(9) — say that three times fast, i dare you 🫶 it's literally the function that adds or removes a buffer from the active list, and she is so dramatic about it (more on that in a sec 😭).

---

✨ NAME ✨

iio_update_buffers — add or remove buffer from active list 🌸

---

🦋 SYNOPSIS 🦋

int iio_update_buffers (struct iio_dev *indio_dev , struct iio_buffer
*insert_buffer , struct iio_buffer *remove_buffer );

that's the whole signature, no cap — copy it exactly, she's picky about her asterisks 💅

---

🎀 ARGUMENTS 🎀

• indio_dev — the device to add buffer to 👑 like, this is the main character device we're doing all this for
• insert_buffer — the buffer to insert 💖 the one sliding into the active list
• remove_buffer — buffer_to_remove 🙈 yeah the original literally wrote it like that, i'm not touching it, she said what she said

---

🌈 DESCRIPTION 🌈

okay so heads up, bestie, because this is the part where it gets real:

Note this will tear down all the buffering and build it up again 💀

like, all of it. gone. then rebuilt. it's giving renovation era, it's giving "we destroyed the kitchen to install a nicer kitchen," it's giving main character energy but make it destructive 🔥 so don't come in expecting a cute lil surgical insert — she's doing a full teardown and rebuild, periodt.

---

⭐ RETURN ⭐

0 on success, or -errno on error 😭 (so if it's not a happy lil zero, the negative errno is telling you exactly what went wrong — iykyk)
