Generally, you should not call this function directly. This only exists to hand off work into SDL as soon as possible, where it has a lot more control and functionality available, and make the inline code in SDL_main.h as small as possible.
Not all platforms use this, it's actual use is hidden in a magic header-only library, and you should not call this directly unless you really know what you're doing.
It is not safe to call this anywhere except as the only function call in SDL_main.
This function is available since SDL 3.0.0.
