snd_pcm_set_state(9)

💖 snd_pcm_set_state(9) 💖

Okay bestie, welcome to the snd_pcm_set_state(9) page from the Kernel API Manual — it’s giving “Set the PCM runtime state with stream lock” and honestly? Iconic. ✨

✨ SYNOPSIS ✨

void snd_pcm_set_state (struct snd_pcm_substream *substream ,
snd_pcm_state_t state );

It’s void, so don’t go looking for a return value, bestie. That’s not the vibe here. 💅

🎀 ARGUMENTS 🎀

• substream — PCM substream. The audio stream in question, slay. 🎧
• state — state to set. Literally the state you’re handing over. ✨
