Use this function to set an application-defined assertion handler.
Syntax
void SDL_SetAssertionHandler(SDL_AssertionHandler handler,
void* userdata)
Function Parameters
handler |

userdata |
a pointer passed to the callback as-is |
Code Examples

Remarks
This function allows an app to show its own assertion UI and/or force the response to an assertion failure. If the app doesn't provide this, SDL will try to do the right thing, popping up a system-specific GUI dialog, and probably minimizing any fullscreen windows.
handler has the following form:
SDL_assert_state YourAssertionHandler(const SDL_assert_data* data, void* userdata)where YourAssertionHandler is the name of your callback function, data is a pointer to the SDL_assert_data struct corresponding to the current assertion, and userdata is what was passed as userdata.
The callback returns an SDL_assert_state value of how to handle the assertion failure.
green
This callback may fire from any thread, but it runs wrapped in a mutex, so it will only fire from one thread at a time.
Setting the callback to NULL restores SDL's original internal handler.
This callback is NOT reset to SDL's internal handler upon SDL_Quit()!
