<title>Description</title>
<para>In addition to the error names user programs define, D-Bus
knows a number of generic, standardized error names that are
listed below.</para>
<para>In addition to this list, in sd-bus, the special error
namespace <literal>System.Error.</literal> is used to map
arbitrary Linux system errors (as defined by <citerefentry
project='man-pages'><refentrytitle>errno</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
to D-Bus errors and back. For example, the error
<constant>EUCLEAN</constant> is mapped to
<literal>System.Error.EUCLEAN</literal> and back.</para>
