💖 SDL_Swap32BE(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where today's main character is SDL_Swap32BE — the little macro that takes your 32-bit value and flips it from bigendian into whatever your machine's native byte order is. it's giving translator, it's giving endianness glow-up. 🦋

✨ NAME ✨

SDL_Swap32BE — swap a 32-bit value from bigendian to native byte order. literally that's the whole job. no cap. 💅

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_endian.h>

#define SDL_Swap32BE(x) SwapOnlyIfNecessary(x)

yes bestie, it's a macro, not a function, and the definition is right there. copy it exactly, don't be cute with it. 🎀

👑 DESCRIPTION 👑

so here's the vibe check: if you're running on a bigendian system, then x comes back to you completely unchanged. nothing happens. it's already home. 🏠✨

this macro also never references x more than once, which means it avoids side effects. so if you were worried about passing something spicy in there and having it evaluated twice — breathe, you're fine. 🫶

🍓 MACRO PARAMETERS 🍓

  • x — the value you wanna swap, and it's gotta be in bigendian byte order already. that's the deal. 🔥

🌈 RETURN VALUE 🌈

returns x, but now in native byte order. glow-up complete. ⭐

💜 THREAD SAFETY 💜

it is safe to call this macro from any thread. no drama, no locks, no stress. periodt. 👑

🧚 AVAILABILITY 🧚

this macro is available since SDL 3.2.0. so if you're on something older... girl, upgrade. 😭

fr fr, that's the whole page. SDL_Swap32BE is small, iconic, and does exactly one thing beautifully. obsessed. 💖

and that's a wrap, bestie! this lil page came from Simple Directmedia Layer, and you're reading the SDL 3.4.18 era of the docs. mwah, take care of your bytes. 💅🎀🦋
