dev_to_iio_dev(9)

✨ dev_to_iio_dev(9) — bestie edition ✨

okay so this is a page from the Kernel API Manual, section 9, and it's genuinely so short you could read it in a TikTok-length attention span 💅 like, one function, one argument, one giant warning. it's giving "small but mighty."

🎀 NAME 🎀

dev_to_iio_dev — Get IIO device struct from a device struct

literally what it says on the tin, bestie. you hand it a struct device and it hands you back the struct iio_dev that device is chillin' inside of. slay.

---

🦋 SYNOPSIS 🦋

struct iio_dev * dev_to_iio_dev (struct device *dev );

---

🌸 ARGUMENTS 🌸

• dev — The device embedded in the IIO device. yes, embedded. it's inside. tucked in. cozy. 🫶

---

💀 NOTE 💀

The device must be a IIO device, otherwise the result is undefined.

no cap, this is the important bit. if what you pass in is not an IIO device, there's no error, no nice little NULL, no warning — the result is just undefined. that's the manpage's way of saying "you're on your own, bestie 🫶". so like, do the vibe check on your device before you call this. iykyk.
