+SDL_RWops work transparently with nacl_io. Two functions control the mount points:
     
-    int SDL_NaClMount(const char* source, const char* target, 
+    int mount(const char* source, const char* target, 
                       const char* filesystemtype, 
                       unsigned long mountflags, const void *data);
-    int SDL_NaClUmount(const char *target);
+    int umount(const char *target);
     
     For convenience, SDL will by default mount an httpfs tree at / before calling 
 the app's main function. Such setting can be overridden by calling:
     
-    SDL_NaClUmount("/");
+    umount("/");
 
 And then mounting a different filesystem at /
