snd_soc_dai_get_stream(9)

✨ NAME ✨

snd_soc_dai_get_stream — bestie, this one retrieves the stream from a DAI 💖

So real quick — we're in the Kernel API Manual, and this page is literally just about grabbing a stream off a DAI. That's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void * snd_soc_dai_get_stream (struct snd_soc_dai *dai , int direction );

That's it. That's the whole call. No cap. ✨

---

🦋 ARGUMENTS 🦋

• dai — the DAI. Just… the DAI. That's the whole description she gave us 💀 (it's a struct snd_soc_dai *, iykyk)
• direction — the stream direction, as in Playback/Capture. Slay, queen, pick a lane 🌈

---

💅 DESCRIPTION 💅

Okay so this routine only retrieves what was previously configured with snd_soc_dai_get_stream 🫶 — that's what the page says, and I'm not gonna editorialize, I'm just the messenger 💖

It returns a pointer to the stream, or an ERR_PTR value. Iconic example: ERR_PTR(-ENOTSUPP) if the callback is not supported 😭 Like, the callback just didn't show up to the party.

Heads up bestie: ERR_PTR means you gotta check that return value with the proper error-checking macros before you dereference it. Don't just raw-dog a void * and start poking at it 💀
