✨ NAME ✨

snd_hda_get_bool_hint — literally just "get a boolean hint value" 🎀

---

🌸 SYNOPSIS 🌸

int snd_hda_get_bool_hint (struct hda_codec *codec , const char *key );

---

🦋 ARGUMENTS 🦋

• codec — the HDA codec, aka the main character here 👑
• key — the hint key string, the thing you're going hunting for 🔍

---

💅 DESCRIPTION 💅

so what it does is: it goes looking for a hint key/value pair that matches the key string you handed it, and then it returns a boolean value parsed from the value. that's the whole serve, no cap ✨

and if there's no matching key? it returns a negative value. not zero, not "eh whatever" — negative. note that fr fr, don't get caught out 🙈
