💖 hdmi_audio_infoframe_check(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, it's giving official energy but we're gonna make it cute 🎀 this one's all about hdmi_audio_infoframe_check, the lil vibes-checker for your HDMI audio infoframe.

✨ NAME ✨

hdmi_audio_infoframe_check — check a HDMI audio infoframe 👑

real talk, that's the whole job: it checks the thing.

🌸 SYNOPSIS 🌸

int hdmi_audio_infoframe_check (const struct hdmi_audio_infoframe *frame
);

that's it, that's the whole signature, she's stunning 💅

🦋 ARGUMENTS 🦋

  • frame — the HDMI audio infoframe. literally the star of the show, the main character, the thing being checked 🫶

💜 DESCRIPTION 💜

so what does she actually do? she validates that the infoframe is consistent — no cap, that's the whole assignment — and she also updates the derived fields (eg. length) based on other fields. so it's not just a check, she's also doing a lil glow-up on the derived stuff on the side ✨

returns 0 on success or a negative error code on failure. so like, zero means slay, negative means something's off 😭
