iio_channel_release_all_cb(9)

okay so welcome to the iio_channel_release_all_cb(9) page from the Kernel API Manual, bestie 💅✨ This is the cleanup moment for an IIO callback buffer: release it, unregister the callback, and let her rest.

🎀 NAME 🎀

iio_channel_release_all_cb — release and unregister the callback. That’s the whole vibe, no cap: release + unregister, no extra side quest 🫶

Note the void, bestie: no return value, she’s all action 💖
