okay so real talk, this is a page straight out of the Kernel API Manual and honestly? it's a little icon and you're gonna love her.

✨ NAME ✨

snd_ac97_update_bits — bestie, this is the one that updates the bits on the given register. that's it, that's the whole job 🫶

🌸 SYNOPSIS 🌸

int snd_ac97_update_bits (struct snd_ac97 *ac97 , unsigned short reg ,
       unsigned short mask , unsigned short value );

look at her go, four arguments, no notes 💖

🎀 ARGUMENTS 🎀

  • ac97 — the ac97 instance. your main character struct, the whole vibe 💫
  • reg — the register to change. like, which drawer are we opening 🗄️
  • mask — the bit-mask to change. the little stencil that says which bits are even invited to the party 🎯
  • value — the value to set. the new fit. the glow-up itself 👑

🦋 DESCRIPTION 🦋

so here's the tea ☕ — she updates the masked-bits on the given register, but only when the value is changed. like, she's not gonna do all that work for nothing. no change, no touch. it's giving "if it ain't broke" energy and honestly? respect 🙈✨

⭐ RETURN ⭐

  • 1 — the bits are changed. slay, we did something 💅
  • 0 — no change. she checked, nothing to do, moving on 😌
  • negative code — failure. not the vibe, something went wrong 💀
