snd_pcm_format_unsigned(9) 💅

okay so hi bestie, welcome to the Kernel API Manual — this page is all about snd_pcm_format_unsigned, and it's literally here to check if a PCM format is unsigned linear. no cap. ✨

🌸 NAME 🌸

snd_pcm_format_unsigned — check the PCM format is unsigned linear, bestie. That's the whole assignment. 🎀

✨ SYNOPSIS ✨

the signature is giving:

int snd_pcm_format_unsigned (snd_pcm_format_t format );

🫶 ARGUMENTS 🫶

• format — the format to check. that's it, that's the argument. 💖

💅 RETURN 💅

okay so the return value has three possible moods:

• 1 — the given PCM format is unsigned linear 💖
• 0 — the given PCM format is signed linear 🎀
• a negative error code — for non-linear formats, bestie 💀
