💅 snd_hda_enum_helper_info

okay so this page is from the Kernel API Manual, section 9, and it's about snd_hda_enum_helper_info — literally the little helper that deals with your simple enum ctls. bestie, it's short, it's sweet, let's go ✨

🌸 NAME

snd_hda_enum_helper_info — the helper for simple enum ctls 🎀

✨ SYNOPSIS

int snd_hda_enum_helper_info (struct snd_kcontrol *kcontrol , struct
snd_ctl_elem_info *uinfo , int num_items , const char * const *texts );

🦋 ARGUMENTS

  • kcontrol — the ctl element, that's her 👑
  • uinfo — a pointer so you can get/store the data, she's holding the info fr
  • num_items — how many enum items we're working with, count 'em 🔢
  • texts — the enum item string array, all the labels live here 🌈

💖 DESCRIPTION

so the whole vibe is: it processes the kcontrol info callback of a simple string enum array. that's the job, that's the assignment 💅

and then the important part — when num_items is 0 or texts is NULL, it assumes a boolean enum array. yes, like that. no cap 🙈

🔥 SEE ALSO

the kernel file lives at ./sound/hda/common/codec.c and honestly the whole friend group is here:

and that's the whole page, bestie 🫶 it ships out of ./sound/hda/common and the date on it is October 2026 — so yeah, future icon behaviour 💀✨ go forth and enumerate, periodt 💜
