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