SDL_GETDEFAULTASSERTIONHANDLER(3)

💖 SDL_GetDefaultAssertionHandler 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where we talk about assertions and the little function that catches them when nobody else volunteered 🫶

---

✨ NAME ✨

SDL_GetDefaultAssertionHandler — get the default assertion handler, no cap 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_assert.h>

SDL_AssertionHandler SDL_GetDefaultAssertionHandler(void);

like. that's it. that's the whole vibe. no arguments, no drama, just vibes and a return value 🌈

---

🦋 DESCRIPTION 🦋

so here's the tea, bestie 🍓

This function hands you back the function pointer that gets called by default whenever an assertion is triggered. It's an internal function that SDL itself provides, and it's the one that steps in for your assertions when SDL_SetAssertionHandler() hasn't been used to swap in a different function.

think of it like the default ringtone on your phone 📱 — it's what plays if you never went into settings and picked something cuter. you can change it (hi, SDL_SetAssertionHandler()), but if you don't, this is the one that shows up. main character energy, honestly.

---

💜 RETURN VALUE 💜

Returns the default SDL_AssertionHandler — the one that gets called when an assert triggers. that's your answer, periodt ✨

---

🔥 THREAD SAFETY 🔥

It is safe to call this function from any thread. go wild, queen 👑 — no locks, no worries, no "not me getting a race condition" moments.

---

⭐ AVAILABILITY ⭐

This function has been available since SDL 3.2.0. so if you're on anything older, sorry babe, it's giving "not found" 😭

lowkey reminder: this page is literally just about getting the default handler. it does not set anything, it does not trigger anything, it does not fix your bugs. it's a getter. that's the whole job. iconic behavior, honestly.

Simple Directmedia Layer 🌸 SDL 3.4.18 — mwah, that's a wrap bestie, go forth and assert responsibly 💖✨🎀🦋
