🦋 iio_channel_get_all_cb(9) — from your Kernel API Manual bestie

okay so. gather 'round. this is iio_channel_get_all_cb, a kernel API function, and it's literally the glow-up moment where you get your triggered-capture callback registered. yes we're doing this. let's go 💅

✨ NAME ✨

iio_channel_get_all_cb — register callback for triggered capture 🎀

like, that's the whole gig. you want a callback firing on triggered capture? this is the door. periodt.

🌸 SYNOPSIS 🌸

struct iio_cb_buffer * iio_channel_get_all_cb (struct device *dev , int
(*cb)(const void *data, void *private) , void *private );

look at her. returns a struct iio_cb_buffer *, takes three things, slays. no cap.

💖 ARGUMENTS 💖

  • dev — pointer to client device. that's your device, bestie. the one you're doing all this for 🫶
  • cb — the callback function. and listen, this one's important: it must be safe to call from any context (e.g. must not sleep). literally do not let it sleep. i'm so serious 😭
  • private — private data passed to callback. your little bag of secrets, hand-delivered to cb 🎀

🌈 DESCRIPTION 🌈

okay so here's the tea, and it's a lil bit of a bummer:

NB right now we have no ability to mux data from multiple devices. so if the channels requested come from different devices this will fail. 💀

that's it. that's the whole description. no muxing across devices yet, so keep your channels on the same device or it's a no from her. periodt.
