StdLib/Include/sys/errno.h

   1 /** @file
   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.
