Question: Where Can I Find Header Files in Linux?
Contents

The C library’s header files include the kernel header files from the “linux” subdirectory. The system’s libc headers are usually installed at the default location /usr/include and the kernel headers in subdirectories under that (most notably /usr/include/linux and /usr/include/asm).

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 <file. h> it should also get it from the right place.

What are header files in Linux?

When a library function is referenced in a source file, the related header files (shown in the synopsis for that function) should be included in that source file. The header files provide the proper declarations for the functions and for the number and types of arguments used with them.
