SDL_GetRenderDrawColorFloat(3)

💖 SDL_GetRenderDrawColorFloat(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_GetRenderDrawColorFloat — she's the one who tells you what color you've been drawing with. 🎨✨

---

🌸 NAME 🌸

SDL_GetRenderDrawColorFloat — get the color used for drawing operations (Rect, Line and Clear). yes gurl, all three of them 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_render.h>

bool SDL_GetRenderDrawColorFloat(SDL_Renderer *renderer, float *r, float *g, float *b, float *a);

like, you hand her a renderer and four little float pointers and she fills them in. float energy only, no cap 🫶

---

🎀 FUNCTION PARAMETERS 🎀

• renderer — the rendering context. the whole vibe, the canvas, the moment. 🖼️
• r — a pointer filled in with the red value used to draw on the rendering target. red alert but make it cute 🍓
• g — a pointer filled in with the green value used to draw on the rendering target. green flag behavior fr 🌿
• b — a pointer filled in with the blue value used to draw on the rendering target. blue era 🦋
• a — a pointer filled in with the alpha value used to draw on the rendering target. the transparency queen, she's giving invisibility realness 👑

not me pointing out that all four of these are pointers that get filled in by the function — so yes, you gotta pass real memory, not vibes. 🫠

🌈 RETURN VALUE 🌈

Returns true on success or false on failure; call SDL_GetError() for more information. if she says false, go ask SDL_GetError() what went wrong, she always spills the tea ☕😭
