/* $Id: */ /** @file * FreeBSD 5.3 * * @changed Commented out stuff which isn't implemented, TCPIP stuff at bottom. * @changed setkey returns void not int in the standard and our implementation (glibc). * @todo Several man-years.. ;) Serious, complete the FreeBSD 5.3 merge and * implement all the functions. Currently there is a bunch of POSIX * #defines missing. */ /*- * Copyright (c) 1991, 1993, 1994 * The Regents of the University of California.
