C equivalent of C++'s double colons?

by

In C, loadSurface would be declared as simply

SDL_Surface *loadSurface(const char *path)

which means the call to SDL_LoadBMP can be written as

SDL_Surface *loadedSurface = SDL_LoadBMP(path);

The details of what std::string does and why .c_str() is needed are not relevant if you are not interested in learning C++, and in this case are not relevant to the tutorial either.
