SDL_SetMainReady(3) SDL3 FUNCTIONS SDL_SetMainReady(3)

SDL_SetMainReady - Circumvent failure of SDL_Init () when not using SDL_main () as an entry point.

Defined in SDL3/SDL_main.h

#include "SDL3/SDL.h"
void SDL_SetMainReady(void);

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.

This function is available since SDL 3.2.0.
