SDL_Swap16BE(3)

💖 SDL_Swap16BE 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where today's main character is SDL_Swap16BE — she takes a 16-bit value and swaps it from bigendian over to whatever byte order your machine is actually vibing with. endianness translation but make it cute ✨

---

✨ NAME ✨

SDL_Swap16BE — swap a 16-bit value from bigendian to native byte order.

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_endian.h>

#define SDL_Swap16BE(x) SwapOnlyIfNecessary(x)

---

🦋 DESCRIPTION 🦋

so here's the tea: if you're running on a bigendian system, then x just gets handed right back to you, unchanged, no notes, no drama. she said "you're already perfect" 💅

and this macro? it never references x more than once, which means no side effects, no sneaky double-evaluation nonsense. it's giving considerate. it's giving respectful. we love that for us 🫶

---

🎀 MACRO PARAMETERS 🎀

• x — the value to swap, in bigendian byte order.

---

🌈 RETURN VALUE 🌈

Returns x in native byte order. periodt.

---

⭐ THREAD SAFETY ⭐

it is safe to call this macro from any thread. go off, concurrent queens 👑

---

💜 AVAILABILITY 💜

this macro has been available since SDL 3.2.0. she's not new new, but she's not ancient either. iykyk.

---

lowkey reminder: byte order stuff is exactly the kind of thing that works fine on your machine and then explodes on someone else's, so fr fr, use the swap macros instead of hand-rolling anything 🙈

---

and that's the whole page, bestie!! no cap, you now understand SDL_Swap16BE better than 90% of people who've ever compiled C 🧚

mwah 💋 — this lil love letter came to you courtesy of Simple Directmedia Layer, SDL 3.4.18, and the SDL_Swap16BE(3) page herself. stay endian-aware out there 💖✨🎀🦋🌸
