SDL_WriteU32LE(3)

💖 SDL_WriteU32LE 💖

okay bestie, so this is a page from the SDL3 FUNCTIONS collection, and honestly? it's giving "tiny but mighty." it's literally just here to help you write 32 bits of data into an SDL_IOStream, in little-endian, no drama. 🦋

---

✨ NAME ✨

SDL_WriteU32LE — use this function to write 32 bits in native format to an SDL_IOStream as little-endian data. periodt. 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_iostream.h>

bool SDL_WriteU32LE(SDL_IOStream *dst, Uint32 value);

---

🎀 DESCRIPTION 🎀

so here's the vibe: SDL byteswaps the data only if necessary — like, it does not do extra work for no reason, she's efficient 💅. that means you, the application, always specify native format, and the data that actually gets written will come out in little-endian format. so you don't gotta worry about the endianness yourself, she handles it. obsessed. ✨

---

🫶 FUNCTION PARAMETERS 🫶

• dst — the stream to which data will be written. (your lil destination 💖)
• value — the data to be written, in native format. (the 32 bits in question, bestie)

---

⭐ RETURN VALUE ⭐

Returns true on successful write, or false on failure 😭 — and if it fails, call SDL_GetError() for more information. she will tell you what went wrong, just ask her. 🥺

---

🔥 THREAD SAFETY 🔥

Do not use the same SDL_IOStream from two threads at once. like, do not. that's not a vibe, that's chaos. 💀

---

🌈 AVAILABILITY 🌈

this function is available since SDL 3.2.0. so if you're on an older version, sorry bestie, you're not getting this one. 🙈

---

and that's the whole page! 🎉 no cap, that's everything. mwah 💋

Simple Directmedia Layer — SDL 3.4.18, that's the source and the version, queen. stay iconic, go write your 32 bits little-endian style 👑✨🦋
