1 Commands Those commands that can be executed by the user from within a shell. 2 System calls Those functions which must be performed by the kernel. 3 Library calls Most of the libc functions, such as qsort(3)) 4 Special files Files found in /dev) 5 File formats and conventions The format for /etc/passwd and other human-readable files. 6 Games 7 Macro packages and conventions A description of the standard file system layout, network protocols, ASCII and other character codes, this man page, and other things. 8 System management commands Commands like mount(8), many of which only root can execute. 9 Kernel routines This is an obsolete manual section.

There are better sources of information for kernel developers.
