snd_pcm_hw_limit_rates(9)

🎀 NAME 🎀

<pink>snd_pcm_hw_limit_rates</pink> — determine rate_min/rate_max fields. Okay bestie, this is the snd_pcm_hw_limit_rates(9) page from the Kernel API Manual, and it is short, sweet, and very “I know exactly what I’m doing” 💅.

🌸 SYNOPSIS 🌸

int snd_pcm_hw_limit_rates (struct snd_pcm_hardware *hw );

🦋 ARGUMENTS 🦋

• hw — the pcm hw instance. That’s the one, bestie 🫶

✨ DESCRIPTION ✨

Okay so this function literally determines the rate_min and rate_max fields from the rates bits of the given hw. That’s the whole vibe check 💖. It’s giving “check the rates bits, set the min and the max, move on” — no drama, no cap. ✨

💜 RETURN 💜

Zero if successful. Slay. That’s the success signal, bestie 😌
