🦋 zpa2326_set_trigger_state — start / stop continuous sampling 💅

okay so bestie, this is a page from the Kernel API Manual (yes, the kernel kernel, we're fancy now ✨) and it's all about one little function: zpa2326_set_trigger_state. It's giving "tiny function, big responsibility" energy and honestly? obsessed. 🎀

✨ NAME ✨

zpa2326_set_trigger_state — Start / stop continuous sampling.

like, that's it. that's the whole job. start it or stop it. icon behavior. 👑

---

🌸 SYNOPSIS 🌸

int zpa2326_set_trigger_state (struct iio_trigger *trig , bool state );

she takes a trigger and a bool and hands you back an int. no cap. 🫶

---

💖 ARGUMENTS 💖

• trig — The trigger being attached to IIO device associated with the sampling hardware. 🦋 think of it as the little connector between the trigger vibes and the IIO device that's actually hanging out with the sampling hardware, iykyk.
• state — Tell whether to start (true) or stop (false). literally a yes/no bestie. true = go, false = stop, no in-between, no "maybe", no "i'll think about it". 💀

---

🧚 DESCRIPTION 🧚

Basically enable / disable hardware continuous sampling mode. that's the whole main character arc right there — flip it on, flip it off. 🔥

Called with IIO device's lock held at postenable or predisable time. ⚠️ so like, don't just roll up and call this whenever, okay? the lock is held at those moments and that's the context this function expects. respect the lock. slay. 💜

---

⭐ RETURN ⭐

Zero when successful, a negative error code otherwise. so <pink>0</pink> = we ate, negative = something went sideways and you should probably look at it. 😭
