snd_hda_jack_add_kctls(9)

💖 snd_hda_jack_add_kctls — the kernel API manual, but make it make sense 💖

okay so bestie, this is a page from the Kernel API Manual (section 9, the kernel-functions girlies 🌸) and it's about snd_hda_jack_add_kctls. literally what it says on the tin: it adds kctls for every single pin that's chillin' inside the pincfg you hand it. no cap. 🎀

✨ NAME ✨

snd_hda_jack_add_kctls — add kctls for all pins included in the given pincfg 💅 (yes, all of them. every last pin. she does not skip.)

✨ SYNOPSIS ✨

look at her go:

int snd_hda_jack_add_kctls (struct hda_codec *codec , const struct
auto_pin_cfg *cfg );

it returns an int, it takes two things, and it's giving "i have a job to do and i'm gonna do it" energy. periodt. 👑

🌸 ARGUMENTS 🌸

• codec — the HDA codec 🎧 like, the actual codec you're working on. that's the main character here, lowkey.
• cfg — the pin config table to parse 🧚 she's the to-do list: our girl snd_hda_jack_add_kctls is gonna walk through this pincfg and set up kctls for every pin she finds in there. iykyk.
