24 * but we also take this opportunity to include a wide selection of

26 * system, work around it here (or better, fix the system or tell
27 * people to use a better one).
38 #error "This header may only be used on UNIX"
46 * Error domain for API in the g_unix_ namespace. Note that there is no
47 * exported enumeration mapping %errno. Instead, all functions ensure that
48 * %errno is relevant. The code for all %G_UNIX_ERROR is always 0, and the
49 * error message is always generated via g_strerror().
51 * It is expected that most code will not look at %errno from these APIs.
52 * Important cases where one would want to differentiate between errors are
53 * already covered by existing cross-platform GLib API, such as e.g. #GFile
54 * wrapping `ENOENT`. However, it is provided for completeness, at least.
