💅 snd_pcm_new_stream(9) 💅

okay bestie, welcome to the Kernel API Manual page for snd_pcm_new_stream(9) — this is the one where we make a brand-new PCM stream ✨

🎀 NAME 🎀

snd_pcm_new_stream — create a new PCM stream 💖

🌸 SYNOPSIS 🌸

int snd_pcm_new_stream (struct snd_pcm *pcm , int stream , int
       substream_count );

🦋 ARGUMENTS 🦋

  • pcm — the pcm instance 🫶
  • stream — the stream direction, SNDRV_PCM_STREAM_XXX 🧭
  • substream_count — the number of substreams 🔢

✨ DESCRIPTION ✨

So this function creates a new stream for the pcm. But listen — the corresponding stream on the pcm must have been empty before calling this. Like, zero must be given to the argument of snd_pcm_new. No cap, that's the vibe check: it has to be empty first, or you are not doing it right 🙈

bestie please remember: empty before you call this. zero to the argument of snd_pcm_new, okay? 💅

🔥 RETURN 🔥

Zero if successful, or a negative error code on failure. That's it, that's the tea ☕✨ periodt.
