NAME
SDL_SetMainReady - Circumvent failure of SDL_Init() when not using SDL_main() as an entry point.
SYNOPSIS
#include <SDL3/SDL_main.h>
void SDL_SetMainReady(void);
DESCRIPTION
This function is defined in SDL_main.h, along with the preprocessor rule to redefine main() as
SDL_main(). Thus to ensure that your main() function will not be changed it is necessary to define
SDL_MAIN_HANDLED before including SDL.h.
AVAILABILITY
This function is available since SDL 3.2.0.
