snd_pcm_hw_rule_noresample(9)

💅 snd_pcm_hw_rule_noresample(9) — the Kernel API Manual ✨

okay bestie, welcome to the Kernel API Manual glow-up for snd_pcm_hw_rule_noresample(9). if you've ever been like "hmm, can the hardware just… not resample at this rate?" — this is literally the function for you. periodt. 🎀

---

🌸 NAME 🌸

snd_pcm_hw_rule_noresample — it adds a rule so you can disable hw resampling. yep, that's the whole vibe. no cap. 💖

---

✨ SYNOPSIS ✨

int snd_pcm_hw_rule_noresample (struct snd_pcm_runtime *runtime ,
       unsigned int base_rate );

it's giving "pass in the runtime, pass in the base rate, get an int back." iconic behavior, honestly. 🦋

---

🎀 ARGUMENTS 🎀

• runtime — the PCM runtime instance, aka the main character of this whole operation 👑
• base_rate — the rate at which the hardware does not resample, fr fr. that's the number you're telling everyone to respect 💅

---

💖 RETURN 💖

Zero if successful, or a negative error code on failure. that's it, that's the deal. zero = slay, negative = something went off and you should check it. 😭
