📦 version 7.3.1, in nixpkgs unstable

💖 drm_rect_overlap(9) 💖

okay bestie, so this is a page from the Kernel API Manual — yes, the actual kernel manual, we're in the big leagues now — and it's about drm_rect_overlap, which is genuinely the most "are we vibing or not" function in all of DRM. it's a little bool-returning icon and honestly it ate. 🎀

✨ NAME ✨

drm_rect_overlap — check if two rectangles overlap 🌸

like, do these two boxes share space or are they living in their own separate eras? that's the whole function. no cap.

🦋 SYNOPSIS 🦋

bool drm_rect_overlap (const struct drm_rect *a , const struct drm_rect *b );

it hands you back a bool. true = they're overlapping, false = they're not. main character energy from a one-line function, we love to see it. 💅

🌈 ARGUMENTS 🌈

  • a — the first rectangle 👑 like, the one you're checking from, yk?
  • b — the second rectangle 🫶 the one you're checking against

both are const struct drm_rect * — const because we're respectful, we're not gonna touch your rectangles, we're just gonna look at them. 🙈

⭐ RETURN ⭐

true if the rectangles overlap, false otherwise.

literally that's it. a vibe check that returns a boolean. 🔥

💜 SEE ALSO 💜

so the actual source of truth lives in the kernel file ./include/drm/drm_rect.h — go drink from the firehose, bestie, it's all there. and while you're at it, meet the whole friend group:

that's the whole squad and every single one of them is invited to the group chat. 💖

ngl if you're out here comparing rectangles without at least glancing at drm_rect_equals(9) too, you're lowkey doing the most. just saying. 💀

okay that's the page!! this one's from ./include/drm, dated October 2026, and it's drm_rect_overlap(9) signing off — mwah, slay, periodt, go check your rectangles 💅✨💖
