Well, it gets more tricky. I've been playing with bumping MAXCOMLEN to 19 (so it uses a total of 20 rather than 17 chars, which is 32-bit aligned) which results in expanding teh size of a structure in the middle of kinfo_proc, which the current kinfo_proc scheme cannot handle. > Bruce -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
