*
* A #GUnixFDList contains a list of file descriptors. It owns the file
* It may be wrapped in a #GUnixFDMessage and sent over a #GSocket in
* the %G_SOCKET_ADDRESS_UNIX family by using g_socket_send_message()
* and received using g_socket_receive_message().
+ *
+ * Note that `<gio/gunixfdlist.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.
