💅 hdmi_audio_infoframe_pack_for_dp(9)

okay so bestie, welcome to the Kernel API Manual — this one's about hdmi_audio_infoframe_pack_for_dp, and honestly? it's giving "tiny function, huge responsibility" energy. 🎀

✨ NAME ✨

hdmi_audio_infoframe_pack_for_dp — packs a HDMI Audio infoframe all cute and ready for DisplayPort 🦋

🌸 SYNOPSIS 🌸

ssize_t hdmi_audio_infoframe_pack_for_dp (const struct
       hdmi_audio_infoframe *frame , struct dp_sdp *sdp , u8 dp_version );

like, that's the whole signature. three args, one ssize_t return, no cap. 💅

🫶 ARGUMENTS 🫶

  • frame — the HDMI Audio infoframe, aka the main character of this whole operation 👑
  • sdp — the Secondary data packet for DisplayPort, i.e. where all the packed goodness ends up 🎁
  • dp_version — the DisplayPort version that's gonna get encoded in the header, so like, the header knows what era it's living in ⭐

🔥 DESCRIPTION 🔥

So what it does: it packs a HDMI Audio Infoframe so it can be sent over DisplayPort. Literally that's it — this function fills the secondary data packet that DisplayPort is gonna use. no extra steps, no side quests, just packing. ✨

💖 RETURN 💖

It hands you back the number of total written bytes — or, if things go sideways, a negative errno on failure 😭 (iykyk, always check your ssize_t, bestie).

fr fr, a negative return means something went wrong, so don't just vibe past it 🙈
