The header files contain the structure definitions for the key components of the virtual file system abstraction. Understanding the contents of these files and the relationships between them is essential to an understanding of virtual file systems. The following are the necessary header files: sys/vfs.

How do I add a header file to a CPP file?

You make the declarations in a header file, then use the #include directive in every

cpp file or other header file that requires that declaration

The #include directive inserts a copy of the header file directly into the

cpp file prior to compilation

How to use header files in C++?

You make the declarations in a header file, then use the #include directive in every

cpp file or other header file that requires that declaration

Should a struct be placed in a header file?

If the struct is only used in one compilation unit (

c file), you place it in that c file

The point is, placing it in a header file allows you to use the structure (or any other definition) from multiple source files, just by including that header file

A header file contains: Function definitions Data type definitions Macros It offer above features by importing them into the program with the help of a preprocessor directive “#include”. These preprocessor directives are used for instructing compiler that these files need to be processed before compilation.
