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
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
