* G_UNIX_ERROR:

* Error domain for API in the g_unix_ namespace. Note that there is no
* exported enumeration mapping %errno. Instead, all functions ensure that
* %errno is relevant. The code for all #G_UNIX_ERROR is always 0, and the
* error message is always generated via g_strerror().
*
* It is expected that most code will not look at %errno from these APIs.
* Important cases where one would want to differentiate between errors are
* already covered by existing cross-platform GLib API, such as e.g. #GFile
* wrapping `ENOENT`. However, it is provided for completeness, at least.
