Seems that the handbook is out of date. Looking at /sys/kern/tty.c the init and lock devices are only used internally and are not real open-able/close-able devices. Thye're created in tty_makedev() as required using make_dev_cred(), which is probably why they appear under /dev. The init device is initialized in tty_init_termios() and _never_ changed after that. It's only used to initialize real ttys. The lock device seems to only be used in tty_ioctl(). I wasn't able to figure out where it gets initialized. -- Gary Jennejohn ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
