  .SH "DESCRIPTION"

    .PP In addition to the error names user programs define, D-Bus knows a number of generic, standardized error names that are listed below.
    .PP 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.

      .PP 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.
