💖 snd_hda_jack_bind_keymap(9) 💖

okay so bestie, we're in the Kernel API Manual today and the star of the show is snd_hda_jack_bind_keymap — literally the function that binds keys generated from one NID to another jack. no cap, that's the whole vibe.

✨ SYNOPSIS ✨

int snd_hda_jack_bind_keymap (struct hda_codec *codec , hda_nid_t
key_nid , const struct hda_jack_keymap *keymap , hda_nid_t jack_nid );

like, she takes four things and returns an int. iconic behavior fr fr 🫶

🎀 ARGUMENTS 🎀

  • codec — the HDA codec 💅 that's your main character here
  • key_nid — the pin NID that generates the key event, aka where the drama starts
  • keymap — the map of key type and key code, so everybody knows which key is which 🦋
  • jack_nid — the pin NID whose jack the key actually reports to — like, the key is born at key_nid but it tells its secrets to this jack's NID 🎀

🌸 DESCRIPTION 🌸

lowkey this one's simple, bestie. This function is used in the case where a key is generated from one NID while it is reported to the jack of a another NID. that's it, that's the whole plot ✨ two NIDs, one key, one jack — the way that this function connects them?? obsessed 😭
