💅 snd_hda_gen_add_kctl(9) 💅

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a little cutie. sit down bestie, we're gonna talk about adding kctls ✨

🌸 NAME 🌸

snd_hda_gen_add_kctl — adds a fresh new kctl_new struct, made from a template 🎀

✨ SYNOPSIS ✨

struct snd_kcontrol_new * snd_hda_gen_add_kctl (struct hda_gen_spec
*spec , const char *name , const struct snd_kcontrol_new *temp );

🫶 ARGUMENTS 🫶

  • spec — your hda_gen_spec object, the main character of this whole operation 💅
  • name — a name string that overrides whatever the template had. if you want to keep the template's name unchanged, just pass NULL 💖
  • temp — the template for the new kctl, i.e. your blueprint 🎀

🔥 DESCRIPTION 🔥

so what this does is it adds a new kctl element to the list living inside spec. and ngl, "kctl" here actually means snd_kcontrol_new — the real thing gets instantiated later, this is just the promise of one 😭. it builds it from the snd_kcontrol_new template temp and the name string name.

and what does it give you back? the newly created object 🫶 — or NULL if something went wrong, which is the error case. lowkey important, so check it, bestie 💀
