Where do header files go?

They go to /usr/include and /usr/lib. If you use the -l option (for the libraries) it should find them from these standard places. If you include using it should also get it from the right place.

Where are header files stored in Windows?

Header files are in the Include folder in your WDK installation folder. Example: C:\Program Files (x86)\Windows Kits\10\Include. The header files contain version information so that you can use the same set of header files regardless of which version of Windows your driver will run on.

What is a #include preprocessor?

The #include directive tells the C preprocessor to include the contents of the file specified in the input stream to the compiler and then continue with the rest of the original file. For example, the header file, file.h contains the following: char *func (void);

What is the purpose of C header files?

Header files serve two purposes. System header files declare the interfaces to parts of the operating system. You include them in your program to supply the definitions and declarations you need to invoke system calls and libraries.

How do I manually install kernel headers?

What is stored in header files?

Header Files: The files that tell the compiler how to call some functionality (without knowing how the functionality actually works) are called header files. They contain the function prototypes. They also contain Data types and constants used with the libraries. We use #include to use these header files in programs.
