## 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.

               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



           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.
