iio_device_claim_direct(9)

💅 iio_device_claim_direct — honestly kinda iconic

okay so this is a page from the Kernel API Manual bestie, and it's all about iio_device_claim_direct, which is lowkey the "keep the device in direct mode" girlie. let me walk you through it 🎀

---

✨ SYNOPSIS ✨

bool iio_device_claim_direct (struct iio_dev *indio_dev );

that's it. that's the whole vibe. one function, one argument, returns a bool. ate and left no crumbs 🫶

---

🌸 ARGUMENTS 🌸

• indio_dev — the struct iio_dev that's associated with the device. yeah she's the main character here, everything runs through her 💜

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — if the device is in direct mode, this function guarantees it's gonna stay that way until iio_device_release_direct gets called. no cap. locked in. the mode is not going anywhere until you say so 🔒✨

use it together with iio_device_release_direct, bestie — they're a matching set, like best friend necklaces but for kernel code 💖

---

⭐ RETURN ⭐

• true on success 🎉 (slay)
• false on failure 😭 (aw)

literally a vibe check in boolean form.
