look at her. clean. simple. three args. no drama. 🎀

🫶 FUNCTION PARAMETERS 🫶

• renderer — the renderer that should draw the point. it's the one holding the pen, basically. 🖊️
• x — the x coordinate of the point. yes it's a float, that's the subpixel thing, we love precision in this house. 💅
• y — the y coordinate of the point. same deal, float, same energy. ⭐

---

🦋 RETURN VALUE 🦋

returns true when it slays (success) or false when it doesn't (failure) 😭 — and if it's giving failure, call SDL_GetError() for more info, she'll tell u what went wrong. fr fr.

and that's the whole page, no cap. this gem lives in the Simple Directmedia Layer collection, version SDL 3.4.18, and it came straight from the SDL_RenderPoint(3) corner of the SDL 3 docs. go draw a point, main character. 🎀🫶
