/** @file\r
  The header <sys/errno.h> defines several values, all relating to the reporting of\r
  error conditions.\r
\r
  The enum members expand to integral constant expressions\r
  with distinct nonzero values, suitable for use in #if preprocessing\r
  directives.  These default values are specified as an enum in order to ease\r
  the maintenance of the values.\r
