Header files should be used to declare objects, functions, typedefs, and macros. Header files shall not contain or produce definitions of objects or functions (or fragment of functions or objects) that occupy storage. This makes it clear that only C files contain executable source code and that header files only contain declarations. A “header file” is defined as any file that is included via the #include directive, regardless of name or suffix.
