Подробное описание

Redefine main() on some platforms so that it is called by SDL.

The application's main() function must be called with C linkage, and should be declared like this:

#ifdef __cplusplus
extern "C"
#endif
int main(int argc, char *argv[])
{
}

Типы

SDL_main_func

Граф вызовов:

SDL_SetMainReady()

DECLSPEC void SDLCALL SDL_SetMainReady

(

void

)

This is called by the real SDL main function to let the rest of the library know that initialization was done properly.

Calling this yourself without knowing what you're doing can cause crashes and hard to diagnose problems with your application.

SDL_RegisterApp()

DECLSPEC int SDLCALL SDL_RegisterApp	(	char *	name,
		Uint32	style,
		void *	hInst
	)

This can be called to set the application class at startup

SDL_UnregisterApp()

DECLSPEC void SDLCALL SDL_UnregisterApp

(

void

)

SDL_WinRTRunApp()

DECLSPEC int SDLCALL SDL_WinRTRunApp	(	SDL_main_func	mainFunction,
		void *	reserved
	)

Initializes and launches an SDL/WinRT application.

Аргументы

mainFunction	The SDL app's C-style main().
reserved	Reserved for future use; should be NULL

Возвращает

0 on success, -1 on failure. On failure, use SDL_GetError to retrieve more information on the failure.

SDL_UIKitRunApp()

DECLSPEC int SDLCALL SDL_UIKitRunApp	(	int	argc,
		char *	argv[],
		SDL_main_func	mainFunction
	)

Initializes and launches an SDL application.

Аргументы

argc	The argc parameter from the application's main() function
argv	The argv parameter from the application's main() function
mainFunction	The SDL app's C-style main().

Возвращает

the return value from mainFunction
