1 organization of this directory is moving towards this approach:
3 <module>.h -- public API and data types
4 <module>_private.h -- protected API and data types
5 <module>.c -- implementation and private API / types
8 .c files may include *_private.h.
9 .h files may not include *_private.h
11 This allows us to have a nicely encapsulated C api with opaque data types and private functions
12 that are nonetheless shared between source files without redundant extern declarations..
