drm_hdmi_avi...display_mode(9)

💖 NAME 💖

okay bestie, so drm_hdmi_avi_infoframe_from_display_mode — yes that's the whole name, it's giving "my parents let me pick my own name and I chose chaos" — literally does one iconic job: it fills an HDMI AVI infoframe with data from a DRM display mode. that's the vibe. no cap. ✨

(this whole page is from the Kernel API Manual, and the function tag is drm_hdmi_avi...display_mode(9) — shortened for the header because the full name would not fit, and honestly same. 💅)

---

🌈 SYNOPSIS 🌈

int drm_hdmi_avi_infoframe_from_display_mode (struct hdmi_avi_infoframe
*frame , const struct drm_connector *connector , const struct
drm_display_mode *mode );

so it takes three pointers and returns an int. that's it. that's the whole signature. she's simple, she's clean, she's serving. 🎀

---

🦋 ARGUMENTS 🦋

• frame — the HDMI AVI infoframe. this is the thing getting filled up with data, she's the main character here fr fr 👑
• connector — the connector. yes, that's genuinely the whole description and honestly? valid. it's the connector. 💀
• mode — the DRM display mode. this is where the data comes from — it's the source material, the inspo, the blueprint 🫶

---

⭐ RETURN ⭐

0 on success, or a negative error code on failure. lowkey the classic Unix contract — zero means we ate, negative means something went sideways 😭

bestie pls always check the return value, a negative number is your code telling you it did not slay.
