{78}  Code example and 2nd paragraph;
The code example on this page returns "Invalid argument"

# ./setconsole 1
./setconsole: ioctl(stdin, TIOCLINUX): Invalid argument

Code correction: 11 is the TIOCL_SETKMSGREDIRECT cmd number

include/linux/tiocl.h:#define TIOCL_SETKMSGREDIRECT       11      /* restrict kernel
messages to a vt */

Also, drivers/char/vt.c explains TIOCLINUX, not tty_io.c
I'm still trying to figure out why it always returns EINVAL.

My kernel version is:
# uname -r
2.6.17-1.2174_FC5
