int snd_pcm_format_set_silence (snd_pcm_format_t format , void *data ,
       unsigned int samples );

like, that's the whole vibe. no cap 🔥

🦋 ARGUMENTS 🦋

  • format — the PCM format 💖 this is the glow-up blueprint, the whole personality of the data we're about to silence-ify.
  • data — the buffer pointer 🎀 this is the bestie we're writing into, the actual memory spot getting the treatment.
  • samples — the number of samples to set silence 🌸 like how many lil slots are getting the silent treatment. iconic.

💜 DESCRIPTION 💜

Sets the silence data on the buffer for the given samples.

that's it, that's the whole plot 😭 it takes your buffer, it takes your format, it takes a sample count, and it drops the silence data right on in there for however many samples you asked for. main character energy, zero drama, just quiet. 🧚

⭐ RETURN ⭐

  • Zero if successful 🎉 slay, we ate, no crumbs.
  • a negative error code on failure 💀 ok so if it's negative something went sideways and you should lowkey check yourself before you wreck yourself.
