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 requested PID is not known.
Added in version 223.
- SD_BUS_ERROR_INVALID_SIGNATURE
The specified message signature is not valid.
Added in version 223.
- SD_BUS_ERROR_INCONSISTENT_MESSAGE
The passed message does not validate correctly.
Added in version 223.
- SD_BUS_ERROR_MATCH_RULE_NOT_FOUND
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.
