SDL_WriteU16LE(3)

💖 SDL_WriteU16LE 💖

okay bestie, welcome to the SDL_WriteU16LE(3) page — it lives in the SDL3 FUNCTIONS section of the manual and it's literally your little endian bestie for 16-bit writes ✨

---

✨ NAME ✨

SDL_WriteU16LE — use this function to write 16 bits in native format to an SDL_IOStream as little-endian data 🎀

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_iostream.h>

bool SDL_WriteU16LE(SDL_IOStream *dst, Uint16 value);

---

🦋 DESCRIPTION 🦋

so the vibe is this: SDL byteswaps the data only if it's necessary. that means you — yes you, the application — always specify native format, and the data that actually gets written lands in little-endian format. no cap. 💅

---

🎀 FUNCTION PARAMETERS 🎀

• dst — the stream to which data will be written. (your destination stream, the place the bytes are going 🫶)
• value — the data to be written, in native format. (native, bestie, not little-endian — SDL handles the rest 😌)

---

⭐ RETURN VALUE ⭐

returns true on a successful write, or false on failure 😭 — and if it fails, call SDL_GetError() for more information. that's your group chat for what went wrong.

---

🔥 THREAD SAFETY 🔥

do not use the same SDL_IOStream from two threads at once. i'm so serious. that's giving chaos and we don't want that energy 💀

---

🌈 AVAILABILITY 🌈

this function is available since SDL 3.2.0 👑

---

lowkey reminder: native format goes in, little-endian comes out, and the byteswapping only happens when it has to. periodt. 💜

---

mwah that's the whole page, you ate it, go write some bytes 🧚 — this came to you from Simple Directmedia Layer, SDL version 3.4.18, dated SDL_WriteU16LE(3). ily, see you in the next manpage 💖✨
