💅 snd_soc_put_volsw_sx(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil' callback that lives in the ALSA SoC side of the kernel, and honestly? she's giving quiet luxury. no cap.

✨ NAME ✨

snd_soc_put_volsw_sx — the double mixer set callback 💖

like, she sets things. double mixer things. you'll see.

🌸 SYNOPSIS 🌸

int snd_soc_put_volsw_sx (struct snd_kcontrol *kcontrol , struct
snd_ctl_elem_value *ucontrol );

that's the whole vibe. two args, one int back. she's lowkey efficient 🦋

🎀 ARGUMENTS 🎀

  • kcontrol — the mixer control 👑 this is the control object you're working with, the main character fr
  • ucontrol — the control element information 🌈 all the juicy info about what value the userland side is trying to hand you

💜 DESCRIPTION 💜

so here's the tea ☕: this is a callback to set the value of a double mixer control that spans 2 registers. two registers. not one. two. she's a little extra like that 💅

Returns 0 for success. that's it, that's the contract. zero means we ate and left no crumbs 🔥
