struct name in the H file, and struct implementation in the C file

Wikipedia:

In object oriented programming languages, encapsulation is used to refer to one of two related but distinct notions, and sometimes to the combination thereof:
- A language mechanism for restricting direct access to some of the object's components.
- A language construct that facilitates the bundling of data with the methods (or other functions) operating on that data.

There is no mechanism for hiding members of a struct.
