1.4 Man Pages

Online manual (man) pages provide immediate documentation about a command, function, subroutine, or collection of such things.

You can display a man page by running the command:

example% man topic

Throughout the C documentation, man page references appear with the topic name and man section number: cc(1) is accessed with man cc. Other sections, denoted by ieee_flags(3M) for example, are accessed using the -s option on the man command:

example% man -s 3M ieee_flags
