system. The indices of the hash are
<itemizedlist>
<listitem><simpara>
sysname - operating system name (e.g. Linux)
</simpara></listitem>
<listitem><simpara>
nodename - system name (e.g. valiant)
</simpara></listitem>
<listitem><simpara>
release - operating system release (e.g. 2.2.10)
</simpara></listitem>
<listitem><simpara>
version - operating system version (e.g. #4 Tue Jul 20
17:01:36 MEST 1999)
</simpara></listitem>
<listitem><simpara>
machine - system architecture (e.g. i586)
</simpara></listitem>
<listitem><simpara>
domainname - DNS domainname (e.g. example.com)
</simpara></listitem>
</itemizedlist>
</para>
<para>
domainname is a GNU extension and not part of POSIX.1, so this
field is only available on GNU systems or when using the GNU
libc.
</para>
<para>
Posix requires that you must not make any assumptions about the
format of the values, e.g. you cannot rely on three digit version
numbers or anything else returned by this function.
