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 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.
