snd_soc_cnew(9)

✨ NAME ✨

snd_soc_cnew — create new control 💅

Like, it literally makes a brand-new control. That's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

struct snd_kcontrol * snd_soc_cnew (const struct snd_kcontrol_new
       *_template , void *data , const char *long_name , const char *prefix );

okay bestie, yes, that return type is a struct snd_kcontrol * and yes, it's a whole lot of characters. copy it exactly, don't @ me. 🫶

---

🦋 ARGUMENTS 🦋

• _template — the control template, aka the blueprint you're copying from. main character of the operation, honestly. 👑
• data — the control's private data. it's giving "personal business, keep it moving." 🙈
• long_name — the control's long name. yes, the long one. 💖
• prefix — the control name prefix, sitting right there at the front like a little label. 🏷️

---

⭐ DESCRIPTION ⭐

So the whole thing is: create a new mixer control from a template control. That's it, that's the function. Template in, control out, slay. ✨

Returns 0 for success, else error. no cap — zero is the good number here. if you get anything else, something went sideways. 😭
