ffb_fillrect(9)

💅 NAME 💅

ffb_fillrect — bestie, this one literally draws a rectangle on the screen ✨

okay so this is section 9 of the Kernel API Manual (the kernel-internals girlies, iykyk) and it's giving "paint a box, but make it kernel space" 🎀

✨ SYNOPSIS ✨

void ffb_fillrect (struct fb_info *info , const struct fb_fillrect *rect
);

no cap, that's the whole vibe — void return, two pointers, we're done 🫶

🦋 ARGUMENTS 🦋

• info — the frame buffer structure that represents a single frame buffer 💖 like, one struct = one frame buffer, that's the whole thing, that's her main character energy 👑
• rect — the structure defining the rectagle and operation 🌸 this is the one that tells you what box and what we're doing to it. she's the blueprint, fr fr

lowkey important: both of these are pointers, so you're passing the structs by reference — not me explaining that, that's just what the synopsis says 💀

👑 SEE ALSO 👑

• Kernel file ./drivers/video/fbdev/ffb.c — the source itself, go read her, she ate 🔥
• ffb_copyarea(9) — the sibling that copies instead of fills
• ffb_imageblit(9) — the one that blits images ✨
• ffb_setcolreg(9) — colours, iconic
• ffb_blank(9) — blanking, the calm-down function 🌈

and that's the whole page, bestie — short and slay 💅 go forth and fill those rects.
