snd_hda_get_path_idx(9)

📦 version 7.3.1, in nixpkgs unstable

✨ snd_hda_get_path_idx ✨

okay so bestie, welcome to the snd_hda_get_path_idx(9) page from the Kernel API Manual 💅 this one's a little baby function but she's lowkey important, so let's get into it 🫶

🌸 SYNOPSIS 🌸

int snd_hda_get_path_idx (struct hda_codec *codec , struct nid_path
*path );

like, that's the whole signature, no cap ✨

🎀 ARGUMENTS 🎀

  • codec — the HDA codec 👑 that's the object you're working with
  • path — a nid_path object 🦋 the path instance in question

💖 DESCRIPTION 💖

okay so here's the tea 🍓: the index this function hands back starts from 1 — it's literally the actual array index with an offset of 1 baked in 🔥 and zero? zero is handled as an invalid path 💀 so if you get a 0 back, that's a vibe check failure, bestie, that path isn't real 🙈

it's giving "off-by-one but make it intentional" and honestly? iconic ✨

⚠️ reminder: 0 = invalid path, always. don't be out here treating it like a valid index, i'm begging 😭
