💖 snd_hda_apply_pincfgs(9) 💖

okay so bestie, welcome to the kernel API manual, and today's main character is snd_hda_apply_pincfgs(9) — literally the function that goes through a whole list of pin configs and sets each one. one by one. no skips. no cap. 🎀

---

✨ NAME ✨

snd_hda_apply_pincfgs — Set each pin config in the given list 💅

that's it, that's the whole vibe. it takes your list and it applies it. every single entry. slay.

---

🦋 SYNOPSIS 🦋

void snd_hda_apply_pincfgs (struct hda_codec *codec , const struct
hda_pintbl *cfg );

look at her. gorgeous. returns void because she's not here to give you feedback, she's here to do the thing. 🫶

🌸 ARGUMENTS 🌸

• codec — the HDA codec. this is the audio codec you're working on, your little guy, your patient. she needs it to know where to apply stuff, iykyk. 🎧
• cfg — NULL-terminated pin config table. literally a table of pin configs that ends when it hits a NULL. think of it like a playlist that stops when it runs out of songs. when it sees that NULL, it knows the list is done, periodt. ⭐

fr fr remember the NULL terminator — that's how she knows when to stop walking the table. no terminator, no chill. 💀
