ALLEGRO_FILE *al_create_file_handle(const ALLEGRO_FILE_INTERFACE *drv,
   void *userdata)

Creates an empty, opened file handle with some abstract user data. This allows custom interfaces to extend the ALLEGRO_FILE(3) struct with their own data. You should close the handle with the standard al_fclose(3) function when you are finished with it.
