tascam_init_pcm(9)

okay bestie, welcome to tascam_init_pcm(9) from the Kernel API Manual — she’s the ALSA PCM init girlie and she’s literally serving ✨

🌸 NAME 🌸

tascam_init_pcm — Initializes the ALSA PCM device. That’s the whole gig, no cap 💅

✨ SYNOPSIS ✨

call her like this, bestie:

int tascam_init_pcm (struct snd_pcm *pcm );

the signature is giving main character energy 🫶

🎀 ARGUMENTS 🎀

• pcm — pointer to the ALSA PCM device to initialize. Like, point her at the device and let her cook 🍓

🦋 DESCRIPTION 🦋

okay so here’s the tea, periodt: this function sets up the PCM operations, adds ALSA controls for routing and sample rate, and preallocates pages for the PCM buffer. Thorough? Very. Obsessed? Lowkey yes 💖

💖 RETURN 💖

0 on success, or a negative error code on failure. So 0 = slay, negative = the error code is telling you what’s up 😭
