iio_device_get_drvdata(9)

💖 iio_device_get_drvdata — get device driver data 💖

okay so real talk, this is a page from the Kernel API Manual (section 9, the kernel-API girlies), and it's honestly such a tiny little function but it's lowkey iconic. stay with me 🫶

✨ NAME ✨

iio_device_get_drvdata — get device driver data 👑

---

🌸 SYNOPSIS 🌸

void * iio_device_get_drvdata (const struct iio_dev *indio_dev );

like, that's it. that's the whole signature. no cap, she's concise 💅

---

🎀 ARGUMENTS 🎀

• indio_dev — the IIO device structure bestie, that's the one you're pulling the data out of 🦋

---

💫 DESCRIPTION 💫

Returns the data you previously set with iio_device_set_drvdata. that's literally the whole vibe — get in, hand back the pointer, get out. she's giving "set it and forget it" main character energy ✨

ngl, this one's a matching-set situation — the getter only makes sense because the setter exists, so go say hi to iio_device_set_drvdata(9) too 💜
