SDL_WasInit(3)

💖 SDL_WasInit(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_WasInit — she's literally just here to tell you what's already up and running ✨

---

🌸 NAME 🌸

SDL_WasInit — get a mask of the specified subsystems which are currently initialized 🫶

(yeah she's nosy, but in a helpful way. she checks who's already at the party 🎀)

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_init.h>

SDL_InitFlags SDL_WasInit(SDL_InitFlags flags);

---

💅 FUNCTION PARAMETERS 💅

• flags — any of the flags used by SDL_Init(); see SDL_Init for details 👑 like, whatever flags you'd throw at SDL_Init, she'll accept them here too. same energy, same set, no cap.

---

✨ RETURN VALUE ✨

Returns a mask of all initialized subsystems if flags is 0 💖 otherwise it returns the initialization status of the specified subsystems 🌈

so basically: pass 0 and she spills the tea on everything that's initialized, pass actual flags and she only reports on the ones you asked about. lowkey iconic behavior.

---

🔥 THREAD SAFETY 🔥

This function is not thread safe. 💀

fr fr, do not come for her from multiple threads at once, she is not built for that chaos. keep it single-threaded or wrap it up yourself, bestie.

---

🌟 AVAILABILITY 🌟

This function is available since SDL 3.2.0 🎀 so if you're on anything older, she's not there yet, sorry bestie 😭

Simple Directmedia Layer 🦋 this whole thing is living in SDL 3.4.18, and the original page signed off as SDL_WasInit(3) — so yeah, that's the vibe, mwah 💖✨ no cap, periodt.
