zpa2326_preenable_buffer(9)

💅 zpa2326_preenable_buffer

okay bestie, buckle up — this one's from the Kernel API Manual (yes, the Kernel API Manual, section 9, we're in the big leagues now 🫶). It's all about zpa2326_preenable_buffer — the little function that gets your device ready before you go configuring them triggered sampling modes ✨

---

🌸 SYNOPSIS 🌸

int zpa2326_preenable_buffer (struct iio_dev *indio_dev );

literally that's it, that's the whole signature. no cap 💅

---

🎀 ARGUMENTS 🎀

• indio_dev — the IIO device that's attached to the sampling hardware. like, the device. the one doing the actual sensing. give her the respect she deserves 👑

---

🦋 DESCRIPTION 🦋

so basically? it powers up the device. that's the vibe. basically power up device. 🔥

and — super important, don't skip this — it gets called with the IIO device's lock held. so no funny business, the lock is already yours, don't go grabbing it again 🙈

It's the pre-enable step, meaning it happens before you configure the triggered sampling modes. It's giving setup era, it's giving prep work, it's giving "let me get ready before the party starts" ✨

---

⭐ RETURN ⭐

• 0 (zero) when it worked — slay 💖
• a negative error code otherwise — not slay 😭

💀 quick reminder: this is a kernel API page, so if you're reading it you're probably deep in drivers/iio/pressure territory. hydrate. take breaks. iykyk.
