That's not all he said.

My man page for gethostname() says that it returns the system's *node*
name, and it has no option to extend this to a fully-qualified hostname
- that's what getdomainname() is for.
It also notes that glibc doesn't implement a separate gethostname()
function, but returns uname -n instead.
AFAIK, uname can not return a domain part.

I think the manual is at best misleading in this statement.
