snd_soc_com...e_bits_async(9)

📦 version 7.3.1, in nixpkgs unstable

✨ snd_soc_component_update_bits_async ✨

okay bestie, so this one's from the Kernel API Manual, section 9 — and yes the header on this page is literally snd_soc_com...e_bits_async(9) because somebody's terminal was too narrow to hold the whole thing. iconic behaviour, honestly. the full name is snd_soc_component_update_bits_async and it's about to eat, so let's go 💅

🌸 NAME 🌸

snd_soc_component_update_bits_async — do a read/modify/write cycle, but asynchronously 🦋

🎀 SYNOPSIS 🎀

int snd_soc_component_update_bits_async (struct snd_soc_component
*component , unsigned int reg , unsigned int mask , unsigned int val );

💖 ARGUMENTS 💖

  • component — the component you're updating, your main character 🫶
  • reg — the register you're updating, like the exact address of the vibe
  • mask — the mask that says which bits you're touching. not all of them. just these. boundaries, queen ✨
  • val — the new value for the bits that mask picked out

🔥 DESCRIPTION 🔥

so basically this function is the sibling of snd_soc_component_update_bits, except the update operation is scheduled asynchronously. that means, and I need you to hear me on this, it may not be completed by the time the function returns 😭

like, the function has already left the group chat and the update is still typing.

if you actually need to be sure every scheduled update has finished, you must call snd_soc_component_async_complete. that's the vibe check. don't skip it, bestie 💀

⭐ RETURN ⭐

  • 1 — the operation was successful and the value of the register changed 🎉
  • 0 — the operation was successful, but the value did not change. no drama, it's fine 🌈
  • a negative error code otherwise 🙈
