complete FQDN of the system is returned with

+The function
+.BR gethostname(2)
+is used to get the hostname. Only when the
+.BR "hostname \-s"
+is called will
+.BR gethostbyname(3)
+be called. The difference in
+.BR gethostname(2)
+and
+.BR gethostbyname(3)
+is that
+.BR gethostbyname(3)
+is network aware, so it consults
+.IR /etc/nsswitch.conf
+and
+.IR /etc/host.conf
+to decide whether to read information in
+.IR /etc/sysconfig/network
+or
+.IR /etc/hosts
+. To add another dimension to this,
+the
+.B hostname
+is also set when the network interface is brought up.
