+ * Support for UNIX-domain (also known as local) sockets.
+ *
+ * UNIX domain sockets are generally visible in the filesystem.
+ * However, some systems support abstract socket names which are not
+ * visible in the filesystem and not affected by the filesystem
+ * permissions, visibility, etc. Currently this is only supported
+ * under Linux. If you attempt to use abstract sockets on other
+ * systems, function calls may return %G_IO_ERROR_NOT_SUPPORTED
+ * errors. You can use g_unix_socket_address_abstract_names_supported()
+ * to see if abstract names are supported.
+ *
+ * Note that `<gio/gunixsocketaddress.h>` belongs to the UNIX-specific GIO
+ * interfaces, thus you have to use the `gio-unix-2.0.pc` pkg-config file
+ * when using it.
