SDL_IOprintf(3)

✨ SDL_IOprintf — the SDL3 glow-up of printf 💅

okay bestie, welcome to the SDL3 FUNCTIONS corner of the SDL_IOprintf(3) manual, where we make formatted printing happen directly into a stream like the icon it is 🎀

---

🌸 NAME 🌸

SDL_IOprintf — print to an SDL_IOStream data stream. that's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_iostream.h>

size_t SDL_IOprintf(SDL_IOStream *context, const char *fmt, ...);

look at that signature. she's giving printf() energy but she writes into a stream, not your terminal. main character behavior, fr fr 💜

---

💖 DESCRIPTION 💖

so basically this function does formatted printing to the stream. like, you hand her a stream and a format string, and she formats your stuff and pushes it straight into that stream. no detours, no drama, just bytes landing where they should 🫶

---

🎀 FUNCTION PARAMETERS 🎀

• context — a pointer to an SDL_IOStream structure. this is your stream, your canvas, your moment ✨
• fmt — a printf() style format string. yes, the classic. the blueprint for what you want written 💅
• ... — additional parameters matching % tokens in the fmt string, if any. so if your format string is asking for stuff, this is where you deliver it 🍓

---

⭐ RETURN VALUE ⭐

returns the number of bytes written, or 0 on failure 😭 and if it fails, bestie, go call SDL_GetError() for more information. she will tell you what went wrong, no cap.

---

🔥 THREAD SAFETY 🔥

⚠️ do not use the same SDL_IOStream from two threads at once. i'm so serious. that's a one-stream-one-thread situation. sharing is not caring here, it's chaos 💀

---

🌈 AVAILABILITY 🌈

this function is available since SDL 3.2.0. so if you're on anything older, she is simply not there yet 🙈

and that's the whole page, mwah 💋 this lil writeup comes to you straight from Simple Directmedia Layer, rockin' SDL 3.4.18 — so go forth, format your bytes, and slay ✨👑
