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.

           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
           The specified bus service name currently 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.

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

           Added in version 223.

       SD_BUS_ERROR_LIMITS_EXCEEDED
           Some limited resource has been exhausted.

           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_AUTH_FAILED
           Authentication did not complete successfully.

           Added in version 223.

       SD_BUS_ERROR_NO_SERVER
           Unable to connect to the specified server.

           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
           The specified network address is already being listened on.

           Added in version 223.

       SD_BUS_ERROR_DISCONNECTED
           The connection has been terminated.

           Added in version 223.

       SD_BUS_ERROR_INVALID_ARGS
           One or more invalid arguments have been passed.

           Added in version 223.

       SD_BUS_ERROR_FILE_NOT_FOUND
           The requested file could not be found.

           Added in version 223.

       SD_BUS_ERROR_FILE_EXISTS
           The requested file already exists.

           Added in version 223.

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

           Added in version 223.

       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
           The requested property does not exist in the selected interface.

           Added in version 223.

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

           Added in version 223.

       SD_BUS_ERROR_UNIX_PROCESS_ID_UNKNOWN

           The specified match rule does not exist.

           Added in version 223.

       SD_BUS_ERROR_MATCH_RULE_INVALID
           The specified match rule is invalid.

           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.

NOTES

       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.
