DESCRIPTION

   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.

   SD_BUS_ERROR_NO_MEMORY
       A memory allocation failed, and the requested operation could not
       be completed.

   SD_BUS_ERROR_SERVICE_UNKNOWN
       The contacted bus service is unknown and cannot be activated.

   SD_BUS_ERROR_NAME_HAS_NO_OWNER
       The specified bus service name currently has no owner.

   SD_BUS_ERROR_NO_REPLY
       A message did not receive a reply. This error is usually generated
       after a timeout.

   SD_BUS_ERROR_IO_ERROR
       Generic input/output error, for example when accessing a socket or
       other I/O context.

   SD_BUS_ERROR_BAD_ADDRESS
       The specified D-Bus bus address string is malformed.

   SD_BUS_ERROR_NOT_SUPPORTED
       The requested operation is not supported on the local system.

   SD_BUS_ERROR_LIMITS_EXCEEDED
       Some limited resource has been exhausted.

   SD_BUS_ERROR_ACCESS_DENIED
       Access to a resource has been denied due to security restrictions.

   SD_BUS_ERROR_AUTH_FAILED
       Authentication did not complete successfully.

   SD_BUS_ERROR_NO_SERVER
       Unable to connect to the specified server.

   SD_BUS_ERROR_TIMEOUT
       An operation timed out. Note that method calls which timeout
       generate a SD_BUS_ERROR_NO_REPLY.

   SD_BUS_ERROR_NO_NETWORK
       No network available to execute requested network operation on.

   SD_BUS_ERROR_ADDRESS_IN_USE
       The specified network address is already being listened on.

   SD_BUS_ERROR_DISCONNECTED
       The connection has been terminated.

   SD_BUS_ERROR_INVALID_ARGS
       One or more invalid arguments have been passed.

   SD_BUS_ERROR_FILE_NOT_FOUND
       The requested file could not be found.

   SD_BUS_ERROR_FILE_EXISTS
       The requested file already exists.

   SD_BUS_ERROR_UNKNOWN_METHOD
       The requested method does not exist in the selected interface.

   SD_BUS_ERROR_UNKNOWN_OBJECT
       The requested object does not exist in the selected service.

   SD_BUS_ERROR_UNKNOWN_INTERFACE
       The requested interface does not exist on the selected object.

   SD_BUS_ERROR_UNKNOWN_PROPERTY
       The requested property does not exist in the selected interface.

   SD_BUS_ERROR_PROPERTY_READ_ONLY
       A write operation was requested on a read-only property.

   SD_BUS_ERROR_UNIX_PROCESS_ID_UNKNOWN
       The requested PID is not known.

   SD_BUS_ERROR_INVALID_SIGNATURE
       The specified message signature is not valid.

   SD_BUS_ERROR_INCONSISTENT_MESSAGE
       The passed message does not validate correctly.

   SD_BUS_ERROR_MATCH_RULE_NOT_FOUND
       The specified match rule does not exist.

   SD_BUS_ERROR_MATCH_RULE_INVALID
       The specified match rule is invalid.

   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.

NOTES

   The various error definitions described here are available as a shared
   library, which can be compiled and linked to with the libsystemd pkg-
   config(1) file.
