drm_rect_equals(9)

💅 drm_rect_equals — bestie, are these two rectangles literally the same??

okay so this one's from the Kernel API Manual, page drm_rect_equals(9), and it's genuinely one of the most chill functions in the whole DRM situation. no cap. it's a vibe check for rectangles. 🎀

---

✨ NAME ✨

drm_rect_equals — determine if two rectangles are equal 🫶

like… that's it. that's the whole job. it looks at two rectangles and tells you if they're twins or not. iconic behavior honestly.

---

🌸 SYNOPSIS 🌸

bool drm_rect_equals (const struct drm_rect *r1 , const struct drm_rect *r2 );

so yeah, it takes two pointers — r1 and r2 — both const struct drm_rect * (const!! it's not gonna touch them, it's a respectful king 👑), and it hands you back a bool. that's the tea. 🍓

---

🦋 ARGUMENTS 🦋

• r1 — first rectangle 💖 (the first one. the OG. the main character of the pair.)
• r2 — second rectangle 💜 (the other one. also important! don't do r2 dirty.)

---

⭐ RETURN ⭐

true if the rectangles are equal, false otherwise.

that's it. no weird edge cases in the docs, no surprise -1, no errno shenanigans. just yes or no. slay. 🔥

lowkey the most refreshing return contract ever — it's giving "I know what I am" energy.
