SDL_ReadS16BE(3)

💖 SDL_ReadS16BE 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_ReadS16BE(3). she's small, she's precise, she reads 16 bits of big-endian data. no cap.

---

✨ NAME ✨

SDL_ReadS16BE — use this function to read 16 bits of big-endian data from an SDL_IOStream and return it in native format. 🎀

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_iostream.h>

bool SDL_ReadS16BE(SDL_IOStream *src, Sint16 *value);

---

🦋 DESCRIPTION 🦋

so here's the tea: SDL byteswaps the data only if necessary, which means the data you get back will be in the native byte order. she's not out here doing extra work for no reason. she's efficient. she's iconic. periodt. 💅

now the sad part 😭 — this function will return false when the data stream is completely read, and SDL_GetIOStatus() will return SDL_IO_STATUS_EOF.

and if false gets returned but 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 you always know what's going on. very demure, very mindful. 🫶

---

🎀 FUNCTION PARAMETERS 🎀

• src — the stream from which to read data. the source, the origin, the place we're getting the goods from. 📥
• value — a pointer filled in with the data read. you hand her an empty cup, she fills it. that's the vibe. 🍓

---

⭐ RETURN VALUE ⭐

Returns true on a successful read, or false on failure — and if it fails, call SDL_GetError() for more info. no guessing, just call the function. 😌

---

🔥 THREAD SAFETY 🔥

Do not use the same SDL_IOStream from two threads at once. like, genuinely. don't. that's not a vibe, that's a race condition. 🙈

---

🌈 AVAILABILITY 🌈

This function is available since SDL 3.2.0. so if you're on anything older, she simply isn't there yet. tragic, but we move. 💀

and that's the whole page, bestie 💜 — brought to you by Simple Directmedia Layer, from the SDL 3.4.18 era, and yeah, this is SDL_ReadS16BE(3) signing off. go read some bytes. you got this. 👑✨
