iio_backend...ampling_freq(9)

🎀 NAME 🎀

okay so bestie, welcome to the iio_backend...ampling_freq(9) page from the Kernel API Manual 💖 this one is literally about iio_backend_set_sampling_freq — Set channel sampling rate ✨ that's the whole assignment, no cap.

✨ SYNOPSIS ✨

the signature is giving “I set the sample rate for a channel” and it's right here:

int iio_backend_set_sampling_freq (struct iio_backend *back , unsigned
       int chan , u64 sample_rate_hz );

💅 ARGUMENTS 💅

• back — the backend device 🫶 your main character struct.
• chan — the channel number, i.e. which channel we're talking to 💫
• sample_rate_hz — the sample rate 🌸 yes, the rate of samples, as advertised.

🫶 RETURN 🫶

0 on success, and a negative error number on failure 😭 so if it's not zero, something went sideways — periodt.
