SDL_BYTEORDER(3)

💅 SDL_BYTEORDER(3) — the SDL3 functions girlies know this one

okay so bestie, welcome to SDL_BYTEORDER 💖 it's a macro, it lives in the SDL3 family of functions, and it literally just tells you which way your target system's bytes are facing. main character energy but make it endianness ✨

---

🌸 NAME 🌸

SDL_BYTEORDER — a macro that reports the target system's byte order. that's it. that's the whole job. she's simple, she's iconic 👑

---

🎀 SYNOPSIS 🎀

#include <SDL3/SDL_endian.h>

#define SDL_BYTEORDER   SDL_LIL_ENDIAN___or_maybe___SDL_BIG_ENDIAN

yes the #define really does look like that. no notes, that's the actual vibe 🦋

---

✨ DESCRIPTION ✨

so this macro gets set to either SDL_LIL_ENDIAN or SDL_BIG_ENDIAN — and ngl, it might get set to other values in the future if some other byte order becomes popular (not me predicting the future or anything, that's just what the docs say 🙈).

the slay part? you can test it with the preprocessor, which means you get to make decisions at compile time instead of running around checking things at runtime like a mess. obsessed.

#if SDL_BYTEORDER == SDL_BIG_ENDIAN
SDL_Log("This system is bigendian.");
#endif

see how that works? compile-time vibe check, no runtime drama 💅

🌈 AVAILABILITY 🌈

this macro has been available since SDL 3.2.0. so if you're on something older, bestie... no she is not there 😭
