/**
 * 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 <literal>0</literal>, 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 <literal>ENOENT</literal>.  However, it is
 * provided for completeness, at least.
