<H2>DESCRIPTION</H2>
|
|
|
|
<P>
|
|
|
|
In addition to the error names user programs define, D-Bus knows a number of generic, standardized error names that are listed below.
|
|
<P>
|
|
|
|
In addition to this list, in sd-bus, the special error namespace
|
|
"System.Error."
|
|
is used to map arbitrary Linux system errors (as defined by
|
|
<B><A HREF="/cgi-bin/man/man2html?3+errno">errno</A></B>(3)) to D-Bus errors and back. For example, the error
|
|
<B>EUCLEAN</B>
|
|
is mapped to
|
|
"System.Error.EUCLEAN"
|
|
and back.
|
|
<P>
|
|
|
|
<B>SD_BUS_ERROR_FAILED</B>
