✨ iio_backend_data_source_get ✨

okay so bestie, welcome to the iio_backend_data_source_get(9) page 💅 this is the kernel API manual for the little function that tells you which data source is currently doing the streaming, and honestly? it's giving "quietly essential" 🎀

int iio_backend_data_source_get (struct iio_backend *back , unsigned int
chan , enum iio_backend_data_source *data );

---

🦋 ARGUMENTS 🦋

• back — the backend device, obvs 🫶
• chan — the channel number, like which lane of the vibe we're checking
• data — a pointer that receives the current source value; it's an out-param bestie, so it gets filled in for you ✨

---
