| 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.
