💖 fb_create_modedb(9) 💖

ok so this is a kernel API manual page, section 9, all about fb_create_modedb — yes bestie, we're in the fb_create_modedb(9) chapter of the Kernel API Manual and it's literally about making a video mode database. slay.

🌸 NAME 🌸

fb_create_modedb — create video mode database 🎀

like, it builds the mode db. that's the whole vibe.

---

✨ SYNOPSIS ✨

struct fb_videomode * fb_create_modedb (unsigned char *edid , int
*dbsize , const struct fb_monspecs *specs );

that's the signature, copy it exactly, don't come for me about the line wrap — that's how it ships 💅

---

🫶 ARGUMENTS 🫶

• edid — the EDID data, bestie. this is the raw goods.
• dbsize — database size. it's an int * and it comes back holding the length of the database (see RETURN below, iykyk).
• specs — monitor specifications, and yes it may be NULL — no monitor specs? totally fine, still valid.

---

👑 RETURN 👑

returns a struct fb_videomode, and dbsize contains the length of the database. so you get the modes and the count. two-for-one, we love to see it 🔥

---

🦋 DESCRIPTION 🦋

ok so what this function actually does: it builds a mode database using the contents of the EDID data. that's it, that's the whole thing. EDID in, mode database out. iconic behavior honestly 💜
