Description A GUnixFDList contains a list of file descriptors. It owns the file descriptors that it contains, closing them when finalized. 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.
