params_rate(9)

🎀 NAME 🎀

okay so bestie, welcome to params_rate(9) — that’s the page, and the manual is the Kernel API Manual. She is iconic for one very specific job: Get the sample rate from the hw params. no cap, that’s the whole assignment 💅

✨ SYNOPSIS ✨

unsigned int params_rate (const struct snd_pcm_hw_params *p );

the way this signature is just sitting there, exact and unbothered. periodt 🎀

🫶 ARGUMENTS 🫶

• p — hw params. that’s it, that’s the argument. she’s the hw params bestie, the main character of the call ✨

🔥 RETURN 🔥

the sample rate. yup, that’s the return value — the sample rate, and nothing else is claimed here. slay 🔥
