SDL_WriteU64LE(3)

💖 SDL_WriteU64LE(3) — SDL3 FUNCTIONS 💖

ok so bestie, welcome to the SDL_WriteU64LE page, straight outta the SDL3 functions manual. this one's a lil baby function that does exactly one job and does it flawlessly. let's get into it ✨

---

🌸 NAME 🌸

SDL_WriteU64LE — use this function to write 64 bits in native format to an SDL_IOStream as little-endian data. that's it. that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_iostream.h>

bool SDL_WriteU64LE(SDL_IOStream *dst, Uint64 value);

yes queen, that's the whole signature. short, sweet, slays 💅

---

🦋 DESCRIPTION 🦋

ok so here's the tea ☕ — SDL byteswaps the data only if necessary. which means you, the application, always specify native format, and SDL handles the rest. the data that actually gets written out will be in little-endian format. no cap. 🫶

so like, don't you dare pre-swap it yourself, bestie. just hand over the native value and let SDL do its thing. it's giving "trust the process" fr fr 💀

---

🎀 FUNCTION PARAMETERS 🎀

• dst — the stream to which data will be written. that's your destination, your little data home, the place the bytes are moving into 🏠
• value — the data to be written, in native format. this is your actual 64-bit number, don't be swapping it, just pass it as-is 🌟

---

⭐ RETURN VALUE ⭐

Returns true on successful write or false on failure 😭 — and if it fails, call SDL_GetError() for more information. that's your little error-message hotline, use it. don't just sit there guessing what went wrong, the info is right there 💖

---

🔥 THREAD SAFETY 🔥

Do not use the same SDL_IOStream from two threads at once. 🚫

for real for real, this is not a drill. one stream, one thread, at a time. sharing is NOT caring in this specific situation bestie, it's undefined-chaos energy and we do not want that 🙈

---

🌈 AVAILABILITY 🌈

This function is available since SDL 3.2.0. so if you're on anything older, it's giving "not yet, babe" — upgrade and you're golden 👑

---

and that's the whole page, bestie!! you understood it, you ate it, you're literally the main character of little-endian 64-bit writes now 💅🌸

mwah, love u, go write those bytes 🫶💜✨
