snd_card_free(9)

🌸 snd_card_free(9) 🌸

okay so this is a page from the Kernel API Manual, and bestie, it's literally the "cleanup era" of soundcard functions 💅 like the final episode where everything gets resolved.

---

✨ NAME ✨

snd_card_free — frees the given soundcard structure 🎀 yes that's it, that's the whole job, and it does it so well.

---

✨ SYNOPSIS ✨

void snd_card_free (struct snd_card *card );

---

✨ ARGUMENTS ✨

• card — the soundcard structure 🦋 (the main character of this whole function, honestly)

---

✨ DESCRIPTION ✨

okay so here's the vibe: this function releases the soundcard structure and all the assigned devices automatically. no cap. 🔥

that means you genuinely don't have to release the devices by yourself — it handles all of that for you, like a bestie who already cleaned your room before you got home 🫶

and the way it's so polite?? this function waits until all the resources are properly released. it doesn't just dip, it makes sure everything is actually done first. patient icon behavior ⭐

---

✨ RETURN ✨

Zero. 😌

and yeah, it frees all associated devices and frees the control interface associated to the given soundcard. so: returns zero, takes everything with it. iconic. 👑
