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.
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.
