SDL_GetAssertionHandler - Get the current assertion handler.

       This function is available since SDL 3.2.0.

       This returns the function pointer that is called when an assertion is triggered. This is either the value
       last passed to

       SDL_SetAssertionHandler (), or if no application-specified function is set, is equivalent to calling

       SDL_GetDefaultAssertionHandler ().

       The  parameter puserdata is a pointer to a void*, which will store the "userdata" pointer that was passed
       to

       SDL_SetAssertionHandler (). This value will always be NULL for the default handler.  If  you  don't  care
       about this data, it is safe to pass a NULL pointer to this function to ignore it.

puserdata
              pointer which is filled with the "userdata" pointer that was passed to SDL_SetAssertionHandler ().
