SDL_WriteU8(3)

💖 SDL_WriteU8 💖

okay bestie, so this is SDL_WriteU8(3) from the SDL3 functions lineup, and it's literally the simplest lil glow-up in the whole I/O world: it writes one single byte to an SDL_IOStream. that's it. that's the whole job. one byte. iconic behavior, no notes. 🦋

---

✨ NAME ✨

SDL_WriteU8 — use this function to write a byte to an SDL_IOStream. fr fr, that's the entire mission statement.

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_iostream.h>

bool SDL_WriteU8(SDL_IOStream *dst, Uint8 value);

---

✨ FUNCTION PARAMETERS ✨

• dst — the SDL_IOStream you're writing to. this is your destination, your vibe recipient, the place the byte is gonna live. 🫶
• value — the byte value you wanna write. literally just the byte. that's the payload. 💅

---

✨ RETURN VALUE ✨

returns true if the write slayed, or false if it flopped. and if it flops, bestie, you gotta call SDL_GetError() for more info — that's where the actual tea is. 😭

---

✨ THREAD SAFETY ✨

⚠️ do not use the same SDL_IOStream from two threads at once. not even for a sec. not even if you're fast. that's not main character energy, that's a race condition energy. 💀

---

✨ AVAILABILITY ✨

this function has been available since SDL 3.2.0. so if you're on something older… girl. upgrade. 🌸

---

and that's the whole page!! mwah 💜

this cutie was brought to you by Simple Directmedia Layer, SDL 3.4.18, and the date on the tin was SDL_WriteU8(3). go write some bytes, bestie. 🎀✨
