snd_pcm_gettime(9)

🎀 NAME 🎀

okay so bestie, this is the Kernel API Manual page for snd_pcm_gettime(9) — and it does exactly what the name says: fills the timespec64 depending on the timestamp mode. no cap, that's the whole vibe. 💅

✨ SYNOPSIS ✨

call it like this, character-for-character, bestie:

void snd_pcm_gettime (struct snd_pcm_runtime *runtime , struct
timespec64 *tv );

the signature ate, periodt. 🫶

🫶 ARGUMENTS 🫶

two args, both lowkey essential:

• runtime — PCM runtime instance. literally the PCM runtime in question.
• tv — the timespec64 to fill. that's the timespec64 you're filling, no cap.
