I want to add API to SDL.
SDL_bool SDL_IsDirectory(const char* dir)
SDL_bool SDL_IsFile(const char* file)

On android, SDL_IsFile uses AssetManager.open(), if success, it is true. But to SDL_IsDirectory, I cannot find proper method. I try to use AssetManager.list(), it too spend CPU, and have to give up.

Is there an effective method to determine path is directory?

I think you can use stat(), but you have to use it on the actual file path because it won't do SDL's asset path magic:

bool ioIsDir(const char* filename)
{
    struct stat status;
    stat(filename, &status);


    return (status.st_mode & S_IFDIR);
}



Called as so:
snprintf(mybuffer, mybuffer_size, "%s/%s", SDL_AndroidGetInternalStoragePath(), "some_directory");

if(ioIsDir(mybuffer))
    ...

(not sure about asset path, because I used SDL_AndroidGetInternalStoragePath(), which returns something more like a config path)

If access directory/file that not app’asset, use stat is OK. But if apply to asset, stat will fail.

The directory is on asset.
