💖 SDL_RenderDebugTextFormat(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, this one is literally called SDL_RenderDebugTextFormat and it's giving "quick and dirty debug text but make it printf" ✨

---

🌸 NAME 🌸

SDL_RenderDebugTextFormat — draws debug text onto an SDL_Renderer. that's it, that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_render.h>

bool SDL_RenderDebugTextFormat(SDL_Renderer *renderer, float x, float y, const char *fmt, ...);

---

🦋 DESCRIPTION 🦋

so what this function does is render a printf()-style format string straight to a renderer. cute right? 🫶

BUT — and I need you to hear me on this one — this is a convenience function for debugging, it has severe limitations, and it is not intended to be used for production apps and games. no cap. do not ship this. 🙈

if you want the full list of limitations and other useful info, go read SDL_RenderDebugText. it's all there, iykyk 👑

💅 FUNCTION PARAMETERS 💅

• renderer — the renderer that should draw the text. she's the main character, she does the drawing 🎨
• x — the x coordinate where the top-left corner of the text will draw 📍
• y — the y coordinate where the top-left corner of the text will draw 📍 (yes bestie, same deal, just the other axis)
• fmt — the format string to draw ✍️
• ... — the additional parameters matching % tokens in the fmt string, if there are any. only if any. periodt 💜

🌈 RETURN VALUE 🌈

returns true on success or false on failure. if it fails, call SDL_GetError() for more info — she will tell you what went wrong, fr fr 😭

---

🧚 THREAD SAFETY 🧚

this function should only be called on the main thread. don't be out here passing it around to your other threads, that's not the move 💀
