SDL_WriteS32LE(3)

💾 SDL_WriteS32LE — the "bestie, just give me the number" function

okay so picture this: you're over in SDL3 land, minding your own business, and you need to shove a 32-bit signed integer into a stream. That's it. That's the whole job. Welcome to SDL_WriteS32LE(3), a member of the SDL3 FUNCTIONS squad. 🫶

---

✨ NAME ✨

SDL_WriteS32LE — bestie, this one writes 32 bits in native format out to an SDL_IOStream, and it lands there as little-endian data. That's the vibe. 💅

---

📜 SYNOPSIS 📜

#include <SDL3/SDL_iostream.h>

bool SDL_WriteS32LE(SDL_IOStream *dst, Sint32 value);

look at her. two args, one bool. so clean. so iconic. ✨

---

🌸 DESCRIPTION 🌸

Here's the tea: SDL only byteswaps the data if it actually needs to. So you, the application, always hand over your value in native format — no manual byte-fiddling, no tears — and the data that gets written comes out in little-endian</little-endian> format. Every time. No cap. 💖

It's giving "trust the process" and honestly? the process ate. 🔥

---

🎀 FUNCTION PARAMETERS 🎀

• dst — the stream that's getting the data written to it. your lil destination. 🦋
• value — the actual data being written, and remember bestie, it goes in native format. don't convert it yourself, she handles it. 💅

---

⭐ RETURN VALUE ⭐

Returns true when the write slayed, or false when it did not. 😭 If you get false, go call SDL_GetError() for the whole story — she'll tell you what went wrong.

---

🧵 THREAD SAFETY 🧵

Do not use the same SDL_IOStream from two threads at once. nope. not today. one stream, one thread, that's the rule. sharing is not caring here, it's giving undefined chaos. 💀

---

🌈 AVAILABILITY 🌈

This function has been available since SDL 3.2.0. she's not new new, but she's not ancient either. ⭐

---

👑 SEE ALSO 👑

you already have everything you need up there, bestie — the SDL_IOStream, the SDL_GetError(), and your own excellent judgement. iykyk. 🎀

mwah 💋 that's a wrap — this page came to you straight from Simple Directmedia Layer, rocking version SDL 3.4.18, and yes the manual page itself is literally called SDL_WriteS32LE(3). go write some little-endian ints, you main character. 🦋✨💖
