SDL_EGLATTRIBARRAYCALLBACK(3type)

💖 SDL_EGLAttribArrayCallback 💖

okay bestie, welcome to the SDL3 DATATYPES corner of the manual — this one's about SDL_EGLAttribArrayCallback, and it's genuinely such a serve once you get it. 🎀

---

✨ NAME ✨

SDL_EGLAttribArrayCallback — the EGL platform attribute initialization callback. it's giving "let the app sneak extra attributes in" energy, fr fr. 🦋

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_video.h>

typedef SDL_EGLAttrib *(SDLCALL *SDL_EGLAttribArrayCallback)(void *userdata);

---

💅 DESCRIPTION 💅

so here's the vibe: SDL is trying to create an EGL context, right? and it's like "hmm, should I let the app add extra attributes to its eglGetPlatformDisplay() call?" and the answer is yes, and this is the callback that makes it happen. main character energy, honestly. 👑

your callback should return a pointer to an EGL attribute array terminated with EGL_NONE. that's the whole assignment. and if this function returns NULL? no biggie — the SDL_CreateWindow process will fail gracefully. slay. 🫶

the returned pointer should be allocated with SDL_malloc() and will be passed to SDL_free(). so like, SDL is gonna free it for you — do not be out here freeing it yourself, bestie. 💀

and the cute part: the arrays returned by each callback will be appended to the existing attribute arrays defined by SDL. so everybody's contributions stack up, no cap. ✨

---

🧚 FUNCTION PARAMETERS 🧚

• userdata — an app-controlled pointer that is passed to the callback. your little personal luggage, you decide what goes in it. 🍓

---

⭐ RETURN VALUE ⭐

Returns a newly-allocated array of attributes, terminated with EGL_NONE. that's it, that's the return. 💖

---

🌈 AVAILABILITY 🌈

This datatype is available since SDL 3.2.0. so if you're on something older... lowkey upgrade. 😭

👑 SEE ALSO 👑

• SDL_EGL_SetAttributeCallbacks(3) — the way that everything ties together, iykyk. 🔥

---

lowkey reminder: SDL_malloc() in, SDL_free() out. hand it over, don't hold it hostage. 💅

and that's the page, bestie! this one came from Simple Directmedia Layer — SDL 3.4.18 — and it's filed under SDL_EGLAttr...rayCallback(3type). periodt. 🎀✨
