DESCRIPTIONIn 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​.

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