在文件外部是否可以看到由'typedef'定义的类型？

Question

http://en.literateprograms.org/Red-black_tree_(C) I got this link and found this definition. typedef rbtree_node node; typedef enum rbtree_node_color color; It is said to be private definition.

I am confused about private property,does it mean the node and color only visible in the file and won't propagate to other files,or just for convenience?

Answer 1

It would be "private" if the typedef would be placed inside a body file. And "public" when it would be placed inside a header file. Private and public don't really exist in C, what they are probably talking about is scope.
