zpa2326_postenable_buffer(9)

✨ NAME ✨

zpa2326_postenable_buffer — configure the device for triggered sampling, bestie 💖

---

✨ SYNOPSIS ✨

int zpa2326_postenable_buffer (struct iio_dev *indio_dev);

---

✨ ARGUMENTS ✨

• indio_dev — the IIO device that's linked to the sampling hardware, okay? 🫶

---

✨ DESCRIPTION ✨

Okay so basically, this function sets up one-shot mode when you're plugging in an external trigger. No external trigger? Then it just lets the internal trigger configure continuous sampling — you can peek at zpa2326_set_trigger_state for that whole vibe. ✨

If an error gets returned, the IIO layer will call our postdisable hook for us, so like, no need to explicitly power the device off here. (Slay, honestly.) 💅

Called with the IIO device's lock held. 🔒

(Called with the IIO device's lock held — yes, that's a thing, don't forget it! 😭)

---

✨ RETURN ✨

Zero when it's all good 👑, or a negative error code if something's off. 💀
