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. 9 10 Copyright (c) 2011 - 2014, Intel Corporation.
