Write your own function? It should just be as simple as creating x*y new surfaces and then blitting from the larger ones to the smaller one.

[source lang = "cpp"]
//Setup SDL and other stuff. . .

SDL_Surface * BigSurface = SDL_LoadBMP("BIGIMAGE.bmp");

SDL_Rect SmallImage;
SmallImage.x = 0;
SmallImage.y = 0;
SmallImage.w = 100;
SmallImage.h = 100;
SDL_Surface * SmallerImage = SDL_CreateRGBSurface(0, SmallImage.w, SmallImage.h, 32, 0 0 0 0); // More info look in the docs

SDL_BlitSurface(BigSurface, &SmallImage, SmallerImage, NULL);
