       chan , enum iio_backend_data_source data );

🎀 ARGUMENTS 🎀

• back — Backend device. the backend device in question, main character energy.
• chan — Channel number. which channel number we're talking about, bestie.
• data — Data source. the data source you're choosing. slay.

💖 DESCRIPTION 💖

okay so a given backend may have different sources to stream/sync data. This function allows you to choose that source. literally choosing the source. periodt. ✨
