SDL_ReadS8(3)

💖 SDL_ReadS8 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where today's main character is SDL_ReadS8 🎀 she's a tiny little function but she's doing the most, fr fr.

---

✨ NAME ✨

SDL_ReadS8 — use this function to read a signed byte from an SDL_IOStream. that's it, that's the whole job, and she ate 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_iostream.h>

bool SDL_ReadS8(SDL_IOStream *src, Sint8 *value);

look at her. two params, one bool, zero drama. iconic 🌸

---

✨ DESCRIPTION ✨

so here's the vibe check: this function will return false when the data stream is completely read, and SDL_GetIOStatus() will return SDL_IO_STATUS_EOF. that's the stream saying "bestie I'm empty, nothing left for you" 😭

but wait — plot twist. if false gets returned and the stream is not at EOF, then SDL_GetIOStatus() will return a different error value, and SDL_GetError() will offer a human-readable message. so like, false doesn't automatically mean "done" — check the status, iykyk 🧚

---

✨ FUNCTION PARAMETERS ✨

• src — the SDL_IOStream to read from. your source, your supply, your stream bestie 🌈
• value — a pointer filled in with the data read. she gets the goods written into her 🍓

---

✨ RETURN VALUE ✨

Returns true on success or false on failure — and if it's a false moment, call SDL_GetError() for more information. lowkey always check, no cap 💀

---

✨ THREAD SAFETY ✨

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

literally do not. she is not built for that kind of chaos, she's a one-thread-at-a-time girlie, periodt 👑

---

✨ AVAILABILITY ✨

This function is available since SDL 3.2.0. so if you're on something older, sorry babe, upgrade 🦋

Simple Directmedia Layer made this one, it's chillin' in SDL 3.4.18, and this whole page is filed under SDL_ReadS8(3) — ty for coming to my ted talk, go read some bytes, ily, bye 💜✨🎀
