SDL_WriteU16BE(3)

💖 SDL_WriteU16BE(3) — the SDL3 functions era 💖

okay bestie, sit down, hydrate, and let me tell you about SDL_WriteU16BE from the SDL3 FUNCTIONS lineup 🎀

---

✨ NAME ✨

SDL_WriteU16BE — the glow-up function you use to write 16 bits in native format into an SDL_IOStream, and have it come out the other side as big-endian data 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_iostream.h>

bool SDL_WriteU16BE(SDL_IOStream *dst, Uint16 value);

---

🦋 DESCRIPTION 🦋

So here's the vibe: SDL byteswaps the data only if necessary. That means you — the application, the main character — always hand over the value in native format, and SDL handles the flipping so what actually gets written is in big-endian format. No cap. You don't do the byte math, SDL does. Iconic behaviour honestly 👑

---

🍓 FUNCTION PARAMETERS 🍓

• dst — the stream to which data will be written 🫶
• value — the data to be written, in native format ✨

---

💜 RETURN VALUE 💜

Returns true on a successful write, or false on failure 😭 — and if it's a fail, call SDL_GetError() for more information, because it will tell you what went wrong, fr fr.

---

🔥 THREAD SAFETY 🔥

Do not use the same SDL_IOStream from two threads at once. That's it, that's the rule. Two threads, one stream = chaos, and not the cute kind 💀

---

⭐ AVAILABILITY ⭐

This function is available since SDL 3.2.0. If you're on anything older, bestie, it's giving "not yet" 🙈
