📦 version 7.3.1, in nixpkgs unstable

💅 hdmi_vendor_any_infoframe_unpack 💅

okay so bestie, welcome to the hdmi_vendor_...frame_unpack(9) page from the Kernel API Manual — yes the title is literally abbreviated with dots in the header, that's not me being lazy, that's just how it is 💖 stay a while, this one's actually cute and short.

✨ NAME ✨

hdmi_vendor_any_infoframe_unpack — unpack a binary buffer into a HDMI vendor infoframe 🎀

🦋 SYNOPSIS 🦋

int hdmi_vendor_any_infoframe_unpack (union hdmi_vendor_any_infoframe
*frame , const void *buffer , size_t size );

literally the whole function signature, untouched, iconic ✨

🌸 ARGUMENTS 🌸

  • frame — the HDMI Vendor infoframe, bestie. this is where the unpacked goodies land 👑
  • buffer — the source buffer, aka the raw bytes we're reading from 🫶
  • size — the size of the buffer, gotta know how much we're working with ngl 💅

💖 DESCRIPTION 💖

so what it does is unpack all the information hanging out inside a binary buffer and pour it into a structured frame of the HDMI Vendor information frame. it's giving "raw bytes → glow-up" energy, honestly 🦋

it also verifies the checksum, as required by section 5.3.5 of the HDMI 1.4 specification — so yeah, it's doing the responsible thing and checking the receipts ✨

returns 0 on success, or a negative error code on failure. no cap, that's the whole contract 😭

🔥 SEE ALSO 🔥

the kernel file lives at ./drivers/video/hdmi.c, and here's the whole friend group of siblings and cousins, fr fr:

like, the entire unpack squad showed up 💜

ngl there's no warnings section on this page, so I'm not inventing one — we keep it honest here 🙈

okay that's the whole thing!! mwah 💋 this page comes from the kernel source tree at ./drivers/video, dated October 2026, and it's filed under hdmi_vendor_...frame_unpack(9) in case you need to find her again 🎀✨🦋
