      2   The header <sys/errno.h> defines several values, all relating to the reporting of
      3   error conditions.
      4 
      5   The enum members expand to integral constant expressions
      6   with distinct nonzero values, suitable for use in #if preprocessing
      7   directives.  These default values are specified as an enum in order to ease
      8   the maintenance of the values.
