SDL_GetAssertionHandler(3)

💖 SDL_GetAssertionHandler 💖

okay bestie, welcome to the SDL_GetAssertionHandler page, part of the SDL3 functions, no cap ✨

---

✨ NAME ✨

SDL_GetAssertionHandler — get the current assertion handler, fr fr.

---

🎀 SYNOPSIS 🎀

#include <SDL3/SDL_assert.h>

SDL_AssertionHandler SDL_GetAssertionHandler(void **puserdata);

---

🌸 DESCRIPTION 🌸

so basically? this hands you back the function pointer that gets called when an assertion is triggered. it's giving "who's on duty right now". 👑

that pointer is either:

• the value you last passed to SDL_SetAssertionHandler(), or
• if literally no application-specified function is set, it's equivalent to calling SDL_GetDefaultAssertionHandler().

and then there's the parameter puserdata — it's a pointer to a void*, and it'll store the "userdata" pointer that was passed to SDL_SetAssertionHandler(). iconic little out-param moment.

heads up: that value will always be NULL for the default handler. periodt.

and if you don't care about this data at all? it is safe to pass a NULL pointer to this function to ignore it. yes bestie, NULL is fine here, the function will simply not fill anything in. 🫶
