bytes_to_samples(9)

💖 NAME 💖

bytes_to_samples(9) — from the Kernel API Manual, bestie — is literally the unit-conversion icon that takes a size from bytes and turns it into samples. That’s the whole serve. ✨

📜 SYNOPSIS 📜

ssize_t bytes_to_samples (struct snd_pcm_runtime *runtime , ssize_t size
       );

🫶 ARGUMENTS 🫶

• runtime — the PCM runtime instance, aka the context bestie you’re working with.
• size — the size in bytes, aka the number getting converted.

🎀 RETURN 🎀

The size in samples. The synopsis also shows the return type as ssize_t. 💅
