hdmi_drm_inf..._unpack_only(9)

okay so bestie, welcome to the Kernel API Manual page for hdmi_drm_inf..._unpack_only(9) — manual name folded in near the top like a good little header replacement, no cap 💅✨

🌸 NAME 🌸

hdmi_drm_infoframe_unpack_only — unpack binary buffer of CTA-861-G DRM infoframe DataBytes to a HDMI DRM infoframe. That's the whole vibe: it's the unpack-only bestie for CTA-861-G DRM infoframe DataBytes, and it's giving “turn these bytes into a structured HDMI DRM infoframe” energy 💖

🎀 SYNOPSIS 🎀

here's the signature, character-for-character, no editing bestie:

int hdmi_drm_infoframe_unpack_only (struct hdmi_drm_infoframe *frame ,
       const void *buffer , size_t size );

💅 ARGUMENTS 💅

• frame — HDMI DRM infoframe. This is the structured frame bestie you're unpacking into 🫶
• buffer — source buffer. The bytes come from here.
• size — size of buffer. Gotta tell it how many bytes are in the source buffer.

🦋 DESCRIPTION 🦋

okay so the actual tea: hdmi_drm_infoframe_unpack_only unpacks CTA-861-G DRM infoframe DataBytes contained in the binary buffer into a structured frame of the HDMI Dynamic Range and Mastering (DRM) infoframe. Literally that's the job — binary buffer in, structured DRM infoframe out, CTA-861-G DataBytes handled, periodt 🦋

Return vibe check: it returns 0 on success or a negative error code on failure. So yes, 0 is the slay, negative is the “nope” 😭
