I am trying to write a method which returns an SDL_Surface*. The code I am using is:
Code:
SDL_Surface* SDLMenu::getSurface() {
	//Create and unlock surface
	SDL_Surface* output = SDL_CreateRGBSurface(SDL_SWSURFACE, 100, 25, 32, 0, 0, 0, 0);
	SDL_UnlockSurface(output);

	SDL_FillRect(output, 0, SDL_MapRGB(output->format, 255, 0, 255));

	SDL_LockSurface(output);

	return output;
}
The problem I have is when I call this function, the output shown is a black screen. Can anyone tell me where I'm going wrong?
Code:
	SDLApplication app;

	SDLMenu menu = SDLMenu();
	SDL_BlitSurface(menu.getSurface(), NULL, app.getScreen(), NULL);

	SDL_Flip(app.getScreen());

	SDL_Delay(10000);

	return 0;
Thanks,
Gary
