       In addition to the error names user programs define, D-Bus knows a
       number of generic, standardized error names that are listed below.
       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 errno(3)) to D-Bus errors and back. For example, the
       error EUCLEAN is mapped to "System.Error.EUCLEAN" and back.
       SD_BUS_ERROR_FAILED
           A generic error indication. See the error message for further
           details. This error name should be avoided, in favor of a more
           expressive error name.
           Added in version 223.
       SD_BUS_ERROR_NO_MEMORY
           A memory allocation failed, and the requested operation could
           not be completed.
           Added in version 223.
       SD_BUS_ERROR_SERVICE_UNKNOWN
           The contacted bus service is unknown and cannot be activated.
           Added in version 223.
       SD_BUS_ERROR_NAME_HAS_NO_OWNER

           Added in version 223.
       SD_BUS_ERROR_NO_REPLY
           A message did not receive a reply. This error is usually
           generated after a timeout.
           Added in version 223.
       SD_BUS_ERROR_IO_ERROR
           Generic input/output error, for example when accessing a
           socket or other I/O context.
           Added in version 223.
       SD_BUS_ERROR_BAD_ADDRESS
           The specified D-Bus bus address string is malformed.
           Added in version 223.

           Added in version 223.
       SD_BUS_ERROR_ACCESS_DENIED
           Access to a resource has been denied due to security
           restrictions.

           Added in version 223.
       SD_BUS_ERROR_TIMEOUT
           An operation timed out. Note that method calls which timeout
           generate a SD_BUS_ERROR_NO_REPLY.
           Added in version 223.
       SD_BUS_ERROR_NO_NETWORK
           No network available to execute requested network operation
           on.
           Added in version 223.
       SD_BUS_ERROR_ADDRESS_IN_USE

           Added in version 223.
       SD_BUS_ERROR_FILE_EXISTS
           The requested file already exists.
           Added in version 223.
       SD_BUS_ERROR_UNKNOWN_METHOD

       SD_BUS_ERROR_UNKNOWN_OBJECT
           The requested object does not exist in the selected service.
           Added in version 223.
       SD_BUS_ERROR_UNKNOWN_INTERFACE
           The requested interface does not exist on the selected object.
           Added in version 223.
       SD_BUS_ERROR_UNKNOWN_PROPERTY

           Added in version 223.
       SD_BUS_ERROR_INTERACTIVE_AUTHORIZATION_REQUIRED
           Access to the requested operation is not permitted. However,
           it might be available after interactive authentication. This
           is usually returned by method calls supporting a framework for
           additional interactive authorization, when interactive
           authorization was not enabled with the
           sd_bus_message_set_allow_interactive_authorization(3) for the
           method call message.
           Added in version 223.
       Functions described here are available as a shared library, which
       can be compiled against and linked to with the
       libsystemd pkg-config(1) file.
       The code described here uses getenv(3), which is declared to be
       not multi-thread-safe. This means that the code calling the
       functions described here must not call setenv(3) from a parallel
       thread. It is recommended to only do calls to setenv() from an
       early phase of the program when no other threads have been
       started.
